Question

In charging by friction, when two neutral bodies are rubbed together:

Options

• Only one body gets charged while the other stays neutral

• Neither body acquires any charge

• Both bodies acquire the same type of charge

• Both bodies acquire opposite charges

Answer 1

In charging by friction, two neutral bodies are rubbed together, causing electron transfer between them. The body that gains electrons becomes negative while the body that loses electrons becomes positive — so both bodies acquire opposite charges. Contact is required in this method.
