Question

Write three methods of charging a body?

Answer 1

1) conduction :- if two body at least one of them is charge comes in contact with each other then both body share charge equally .
2)induction :- develop due to connection with earth but never connected with charge body

3)friction:- develop by rubbing of two objects

Answer 2

Making a body to acquire property of attracting small objects is called charging(or electrification). A body can by charged by the following ways:
By rubbing: When a body is rubbed with another body, both of them charged. One of the bodies acquires positive charge and the other acquires negative charge. For example, when a glass rod is rubbed with a silk, the glass rod acquires positive charges,and at the same time, the silk,the silk acquires negative charges.
By conduction:When an uncharged body is made in contact with a charged body flow into the non charged body and the body is charged. For example ,if an uncharged sphere A is made in contact with a charged sphere B, the sphere A will be charged sphere B, the sphere A will be charged with the same charge as in the sphere B.
By induction:When a charged particles or body is brought near non charged body without touching, charges are developed in the uncharged body.This method of charging a body is called charging by induction.
