By convention, we call one type of charge “positive”, and the other type “negative.” For example, when glass is rubbed with silk,
the glass becomes positively charged and the silk negatively charged
. … A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged.
What will happen if a glass rod is rubbed on a silk cloth?
Solution: When a glass rod is rubbed with silk,
glass rod loses electrons and silk gains electrons
. Glass rod becomes positively charged and silk becomes negatively charged.
When a glass rod is rubbed with silk cloth charges appear on both a similar?
Since the magnitude of positive charge on the glass rod is the same as that of negative charge on the silk, the net charge on the
system is zero
. Thus the appearances of charge on the glass rod and the silk cloth is in accordance with the law of conservation of charges.
What happens when a silk cloth is used to rub a glass rod and the rod is then brought near an inflated balloon?
When we rub glass rod with silk cloth and bring it near an inflated balloon then
glass rod will acquire positive charge
. Because transfer of electrons takes place from glass rod to silk cloth thereby leaving glass rod positively charged. … That’s why the glass rod can induce a net negative charge on inflated balloon.
What happens when a glass rod rubbed with silk cloth is brought near bits of paper and why?
Rubbing the glass with the
silk charges the glass positive
, and the glass rod thus charged attracts the paper bits in the same way that the plastic rod does.
What will happen if a glass is made from cloth?
Answer: When glass rod is rubbed with silk, glass happens
to lose electrons easily
and silk grabs them away from the glass atoms. So after rubbing, the glass becomes positively charged and the silk becomes negatively charged.
When we rub glass rod with fur the glass rod will acquire?
When rubbed with fur,
glass will become negatively charged
. However if silk is used instead of fur, glass will acquire a positive charge.
How does the glass rod appear?
When light passes from air into glass, it slows down. It’s this change in speed that causes the light to reflect and refract as it moves from one clear material (air) to another (glass). … No reflection and no refraction will take place, and the object will be invisible.
When a glass rod is rubbed with a silk cloth charges appear on of both A similar phenomenon is observed with many other pairs of bodies explain how this?
The net charge on the system of two rubbed bodies is zero. This is because equal amount of opposite charges annihilate each other. When a glass rod is rubbed with a silk cloth,
opposite natured charges
appear on both the bodies. This phenomenon is in consistence with the law of conservation of energy.
When a glass rod is?
When glass rod is rubbed with silk, glass happens to lose electrons easily and silk grabs them away from the glass atoms. So after rubbing, the glass becomes
positively charged
and the silk becomes negatively charged. Thus equal but opposite charge are produced on the both.
Why do electrified glass rod and silk cloth when brought in contact no longer attract each other?
the surface of a
glass is very smooth
hence the electrons are very loosely attached to its surface . hence when a glass rod is rubbed against the silk cloth , glass rod looses electrons and become positively charged and the silk cloth becomes negatively charged.
When a glass rod rubbed with silk and a plastic rod rubbed with fur are brought closer they attract each other why?
When an ebonite rod is rubbed with fur it starts gaining electrons and therefore obtains negative charge and when glass rod is rubbed with silk cloth it starts losing electrons and therefore obtains positive charge. Therefore, by the law of static electric charges,
two opposite charged objects
attract each other.
What happens when someone rubs glass rod with a piece of silk and is brought near a negatively charged paper cylinder?
The glass rod becomes positively charged, while the cloth will have a negative charge. Glass happens to lose electrons easily, and silk grabs them away from the glass atoms, so after rubbing the glass becomes positively charged and the
silk
becomes negatively charged.
How does a glass rod after being rubbed on silk exerts force on another charged object?
Glass happens to lose electrons easily, and silk grabs them away from the glass atoms, so after rubbing the
glass becomes positively charged
and the silk becomes negatively charged.
Is glass a textile?
Glass is
an incombustible textile fiber
and has high tenacity too. It has been used for fire-retardant applications and also is commonly used in insulation of buildings. Because of its properties and low cost, glass fiber is widely used in the manufacture of reinforcement for composites.
What material is glass cloth?
Glass cloth is a
textile material woven from fiberglass yarn
.
Can you make cloth out of glass?
Glass
fiber lends itself to woven fabric because the thin fibers can easily bend. Fabric made of glass fibers has high tensile strength, dimensional stability, high heat and fire resistance, as well as resistance to many chemical compounds.
What are the 3 purposes of a glass rod?
- Used for stirring. In order to accelerate the mixing of the chemicals and liquids, glass rods are used to stir.
- Used for electrification experiment. Rubbing fur and silk can easily estimate the positive and negative electricity.
- Used to spread liquid evenly into somewhere. …
- Used to produce sight glass.
Why glass or Ebonite generates electricity when rubbed with silk or fur?
How and why glass or ebonite when rubbed with silk or fur generate electricity or gain or lose negative charge? … In the
glass rod the electrons are found to be less tightly bound in comparison to silk
, hence electrons gets removed from glass rod and transferred to silk, and the glass rod acquires a positive charge.
Why is glass invisible?
Whenever light encounters an abrupt change in refractive index (how much a ray of light bends as it crosses from one material to another, such as between air and glass), a portion of the light is reflected. …
Reflections are reduced so much
that the glass essentially becomes invisible.
Why does refraction occur?
Light refracts
whenever it travels at an angle into a substance with a different refractive index (optical density)
. This change of direction is caused by a change in speed. … When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction.
When a glass rod is rubbed with silk is brought near the gold leaf?
Charge on glass rod
is positive
, so charge on gold leaves will also be positive. Due to X-rays, more electrons from leaves will be emitted, so leaves becomes more positive and diverge further.
What happens when amber is rubbed with silk?
When amber is rubbed with wool or silk,
amber becomes positively charged
. … (c) Like charges repel each other while the unlike charges attract each other.
What happens when a glass rod is rubbed with wool?
When we rub a glass rod with wool,
the electrons go into the wool from the glass rod
. In other words, there is an excessive number of positively charged particles in the glass rod compared to negatively charged particles.
What would happen if a neutral glass rod is brought near a positively charged glass rod?
Since the electrostatic force decreases with distance, the repulsion of like charges is weaker than the attraction of unlike charges, and so there is a net attraction. Thus, a positively charged glass rod
attracts neutral pieces of paper
, as will a negatively charged rubber rod.
What happens when a glass rod rubbed with silk is brought close near a plastic pen rubbed with Woollen cloth suspended freely?
Friction Charges Both the Objects Which are Rubbed Together
1) When a glass rod is rubbed with a silk cloth, then both,
the glass rod as well as the silk cloth get charged
. The charged glass rod can attract tiny pieces of paper and the charged silk cloth can also attract tiny pieces of paper.
What happens between a plastic rod rubbed with a piece of animal fur?
What happens to a plastic rod when it is rubbed with a piece of animal fur? What happens to the piece of fur?
The plastic rod becomes negative, and the fur becomes positive
(the magnitude of each charge is the same). … The magnitude of the charge on each object is the same, and it is of opposite sign.
What happens when plastic rod is rubbed with fur?
In case of the plastic rod and the fur,
the negatively charged electrons from fur move to the plastic rod making it negatively charged and simultaneously leaving the fur with concentration of positively charged particles
.
What happens when you rub a plastic rod with a cloth?
When a plastic rod is rubbed with a cloth, the
plastic rod becomes negatively charged as electrons from the cloth are deposited on the plastic rod
.
