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 futher.
When a glass rod rubbed with silk is brought near the gold leaf Electroscope the leaves diverge What is the charge on the leaves?
As charge on glass rod is
+(ve)
so charge on gold leaves will also be +(ve). Due to X-rays more electrons from leaves will be emitted, so leaves becomes more positive and diverge further.
When a glass rod rubbed with silk is brought near the knob of a positively charged gold leaf?
Because when the positively charged glass rod is touched on the disc of a negatively charged gold leaf electroscope, the electrons shifts towards rod, hence amount of charge on gold leaves
decreases
and the divergence between the gold leaves decreases as unlike charges attract each other.
When a glass rod rubbed with silk is brought near?
Correct option a attraction Explanation:When the glass rod is rubbed with silk the rod
acquires positive charge
and when the rubber rod is rubbed with wool the rod acquires negative charge. Again when the glass rod and rubber rod are brought close they attract.
What charge will be developed on the leaves of the electroscope if a gold leaf Electroscope is charged by conduction using a glass rod rubbed with silk?
A glass rod rubbed with silk is used to charge a gold leaf electroscope and the leaves are observed to diverge. The electroscope thus charged is exposed to X-rays for a short period. Then. Charge on glass rod is
positive
, so charge on gold leaves will also be positive.
What types of charges do we find in gold leaf electroscope if we bring glass rod near to it?
When the
negatively
-charged rod is brought close to the electroscope, positive charges are attracted to it and negative charges are repelled away from it.
What will happen when the metal top of an electroscope is touched with a glass rod which has been rubbed with silk cloth explain?
(a) When a glass rod is rubbed with a silk cloth,
it acquires positive charge
. When it is touched with the metal top of an electroscope, both the metal top and leaves acquires a positive charge due to conduction.
When the glass rod is rubbed with silk the silk strips electrons from the rod leaving it a positive charge?
Friction Charges
Both the Objects Which are Rubbed Together The electric charge acquired by a glass rod (rubbed with silk) is positive charge whereas the silk cloth gets a negative charge. 2) When we rub a ballpoint pen refill with a piece of polythene, then both, the refill as well as polythene get charged.
What happens when you put a negatively charged thing next to a positively charged thing?
When a negatively charged object is brought near a positively charged object,
an attractive force is produced
. … Since both leaves are negatively charged, they repel each other. When the rod is removed, the electroscope will remain charged because of the extra electrons added to it.
Why do objects become positively and negatively charged?
An electrical charge is created when electrons are transferred to or removed from an object.
Because electrons have a negative charge
, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.
What happens when a plastic rod rubbed with dry hair and a glass rod rubbed with silk are brought near to each other?
Since, both glass rod and fur are positively charged and like
charges repel each other
. So, both the glass rod and fur will repel each other.
What would happen if a plastic rod rubbed with fur is brought near a glass rod rubbed with silk?
A glass rod rubbed with silk gets
a positive charge
. A plastic rod rubbed with fur gets a negative charge. … A charged plastic rod, however, attracts it. This mysterious force is called the electric force.
What happens when an ebonite rod is rubbed with silk?
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.
Why does a glass rod gets positively charged when rubbed with silk?
When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. … On rubbing together, the glass rod loses 2 electrons and silk gains 2 electrons. Now the glass rod
has 8 electrons and 10 protons
which makes it positively charged.
How can you tell if an electroscope is positively or negatively charged?
If you bring a positive object near the electroscope,
it will attract the electrons toward the terminal
. The leaves will move away from each other. … In this case, grounding the electroscope with your finger will allow extra electrons to move to the electroscope, which will become negatively charged.
What happens when you touch an electroscope with your finger?
The leaves of an electroscope collapse as soon as we touch the metal cap with hand because the leaves of the charged electroscope lose charge to the earth through our body. This process is known as
EARTHING
.
