Identify the following, the processes which can be used to charge an uncharged body.
(1) Conduction (2) Induction (3) Friction (4) Repulsion
Only (1), (2) and (3)
There are three processes to charge an uncharged body:
Charging by friction/rubbing
i) When two bodies are charged by rubbing, they acquire equal & opposite charges.
ii) The body which loses electrons acquires positive charge whereas the body which gains electrons acquires a negative charge.
Charging by conduction: Charging a neutral body by bringing it in contact with a charged body is called charging by conduction.
Charging by induction: Charging a neutral body by bringing it near a charged body is called charging by induction.
