Is paper positive or negative charge?
The bits of paper are electrically neutral, but when you bring the rod close to them, even though paper is not a conductor, that is, the charges within it are not free to move about as a current, the negative charges have enough mobility that they are repelled by the rod.
Why is paper attracted to a charged rod?
A positively charged rod is brought near a piece of paper. When the positively charged rod is brought near the neutral paper, it induces a negative charge on the side of the paper nearer to the rod. Since unlike charges attract each other, the paper will be attracted to the rod.
What happens to the electrons when a plastic rod is charged negatively using wool?
Charging the plastic rod negative by rubbing it with the wool exciter leaves a net positive charge on the wool, so that if you place the rod on a swivel stand, you can then bring the wool exciter close to it and pull it around on the swivel stand.
Why is the uncharged sphere attracted to the negatively charged rod?
An uncharged metal sphere has free electrons that can move around inside it. When a negative rod is brought near an uncharged metal sphere, the electrons in the sphere are pushed away from the side of the sphere closest the rod and move to the other side of the sphere.
What is the positive or negative state of an object?
Positively charged objects have electrons; they simply possess more protons than electrons. Negatively charged objects have protons; it’s just their number of electrons is greater than their number of protons.
What happens when you rub a metal rod with a cloth?
How does a rod get charged when rubbed with a cloth? This happens when a negative charge (later we will see that negative charges are associated with electrons) is transferred from first body to the second, the first body charged positively, and the second body is charged negatively.
Can two bodies with like charges attract each other?
(a) yes. Two bodies are placed close to each other where one has much more charge than the other. Then due to induction, force of attraction becomes more than force of repulsion.
