Question

Mention 3 ways by which a body can be charged

Answer 1

Following are the three important ways by which a body can get charged.
⇒By conduction:When an uncharged body is made in contact with a charged body, the charge flow into the non charged body and the body gets charged.
⇒By rubbing: When a body is rubbed with another body, both of them gets charged. One of the bodies acquires positive charge and the other acquires negative charge.
⇒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.

Hope this helps.
