Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. Like
charges repel
(the two balloons, once charged, will move away from each other) and opposite charges attract (the paper will be attracted to the charged balloons.)
What happens when you rub 2 balloons on your hair?
Rubbing the balloon against hair
causes electrons to move from the hair to the balloon
. Because electrons are negatively charged, the balloon acquires a negative charge, while the hair, with its loss of negative charges, now has a net positive charge. … That’s why the hair gets pulled toward the balloon (Figure 2).
What happens to your hair if you rub it against a balloon?
When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. … Similarly, when you rub a balloon on your head it
causes opposite static charges to build up both on your hair
and the balloon.
What happens when you move the two balloons near each other after rubbing?
When you rub two things together you can
move the negatively charged electrons from one material to another
. … When you rub both balloons, both end up with negative charge. Similar charges repel so the balloons push away from each other. You can even use one balloon to push the other around!
What would happen if you charged a balloon by rubbing it against your hair and then brought it near another balloon that is neutral explain?
The balloon is charged by rubbing it on your hair. When you put it near a neutral object (paper, Styrofoam or puffed rice cereal),
the electrons in the object repel away from the balloon and the protons are attracted to the balloon
. … The negatively charged balloon is then attracted and will “stick” to the object.
Why would a balloon attract your hair without touching it?
When a rubber balloon is rubbed against human hair, electrons are transferred from the hair to the rubber, giving the balloon a net negative charge, and leaving the hair with a net positive charge. As the balloon is pulled away,
the opposite charge on the hair causes
it to be attracted to the balloon.
What happens to the stream of water when you hold the charged balloon next to it?
When you bring the charged balloon near to the water it pushes electrons away,
leaving a positively charged area which is attracted to the balloon
. The water coming from the tap is neutral with positive and negative charges. … This positively charged water is attracted to the balloon so the stream is deflected.
Is rubbing a balloon on your head friction?
Electrostatic charges are not caused by friction, although many assume this to be the case. Rubbing a balloon on your head or dragging your feet on the carpet will build up a charge, but so will ordinary walking or repeatedly touching your head with a balloon! …
Friction has nothing to do with the charge
.
Is a balloon negatively or positively charged?
When you rub a balloon on a sweater, for example, some electrons come off and end up on the balloon. The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a
negative charge
. Since electrons have a negative charge, the balloon now has a negative charge.
Why do balloons stick to the ceiling?
There is no glue, no string and the wall is not positively charged like our hair is at the moment (still looking funny, huh?). A balloon sticking to the ceiling. … The
negatively charged balloon repells the electrons in the wall
, leaving only positive ions which attract the balloon and make it stick to the wall.
What two charges attract each other?
If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result
opposite charges
attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.
What happens when you touch a metal doorknob after rubbing your shoes on the carpet?
Friction between your shoe and the wool causes a transfer of electrons from the carpet to you. … When you touch the metal knob, electrons suddenly move from your body through your fingertips to the metal doorknob as
a static discharge
.
What happens to two charged objects when rubbed together?
When two different materials are rubbed together, there is
a transfer of electrons from one material to the other material
. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).
When you walk across a carpet electrons rub off the carpet onto your shoes when this happens which becomes negatively charged the carpet or your shoes?
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet,
your body collects extra electrons
. The electrons cling to your body until they can be released. As you reach and touch your furry friend, you get a shock.
How does a body becomes positively 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.
When an object is attracted to a negatively charged balloon?
A negatively charged object would never be attracted to a – balloon
. However, a + object would be attracted to a – balloon (opposites attract) and a neutral object would be attracted to a – balloon (since neutral objects are attracted to any charged object).
