When a plastic rod is rubbed with wool the wool becomes positively charged?
Electricity and Magnetism Test
| A | B |

| An object is charged positively when rubbed with a piece of silk. The object became charged by | losing electrons |
| When a plastic rod is rubbed with wool, the wool acquires a positive charge because | electrons are transferred from the wool to the rod. |
What happens when plastic is rubbed with wool?
when plastic is rubbed with wool than plastic will will get negatively charged. It is because electrons in wool are less tightly bond than electrons in plastic rod.
Is wool positively or negatively charged when rubbed?
Silk tends to give things a positive charge, and wool tends to give a negative charge.
What is attracted to a plastic rod rubbed with wool?
A (charged) plastic rods rubbed with wool is attracted to an un-rubbed (neutral) plastic rod. A plastic rod rubbed with wood is attracted to the wool, repelled by the silk. No charged (rubbed) object attracts both the charged plastic rod and the charged glass rod.
Is plastic negative or positive?
If you rub a glass rod with a cloth, the charge produced on the glass rod is called positive, whereas when a plastic rod is rubbed with a cloth, the charge produced on the plastic rod is negative.
Why does a plastic rod become negatively charged?
For example, when a plastic rod is rubbed with a duster, electrons are transferred from one material to the other. The material that gains electrons becomes negatively charged. The duster picks up electrons from the rod. This leaves the rod with a positive overall charge and the duster with a negative overall charge.
When a plastic rod rubbed with wool is brought near the knob of a negatively charged gold leaf electroscope The gold leaves will?
When a platic rod is rubbed with wool the rod gains negative charge and wool gains positive charge . So the rod repels negative charge from the top of the electroscope this causes excess of negative charge on leave the leaves having the same charge are repelled and dilated.
What kind of charges are produced on each when Ebonite rod is rubbed with wool?
On rubbing an ebonite rod with wool, the electrons from the wool get transferred to the ebonite rod. The wool gets a deficiency of electrons and so it gets positively charged. On the other hand, the ebonite rod gets excess electrons and hence it gets negatively charged.
When a plastic rod is rubbed with fur The plastic rod becomes negatively charged?
When you rub a plastic rod with fur, the plastic rod becomes negatively charged and the fur becomes positively charged. As a consequence of rubbing the rod with the fur, the rod gains mass and the fur loses mass. the electric force between charged particles decreases with increasing distance.
Is plastic positively or negatively charged?
Choice of the names negative or positive is arbitrary. If you rub a glass rod with a cloth, the charge produced on the glass rod is called positive, whereas when a plastic rod is rubbed with a cloth, the charge produced on the plastic rod is negative.
How does a plastic rod gain charge when rubbed?
When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy. Electrons gain enough energy to leave the atom and ‘rub off’ onto the polythene rod. The polythene rod has gained electrons, giving it a negative charge. The duster has lost electrons, giving it a positive charge.
Is wool negatively charged?
Wool is a conductive material, which means it readily gives away its electrons. Consequently, when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon’s surface. The rubbed part of the balloon now has a negative charge.
