Final answer:
When a charged body is brought close to an uncharged body without touching it, a temporary charge may result on the uncharged body. When a charged body is brought into contact with an uncharged body and then is removed, a permanent charge may result on the uncharged body.
Step-by-step explanation:
When a charged body is brought close to an uncharged body without touching it, a temporary charge may result on the uncharged body. This is known as charging by induction. The charged body induces a separation of charges in the uncharged body, with opposite charges being attracted to the charged body and like charges being repelled.
When a charged body is brought into contact with an uncharged body and then is removed, a permanent charge may result on the uncharged body. This is known as charging by contact. The charged body transfers some of its charge to the uncharged body, resulting in the uncharged body acquiring the same type of charge as the charged body.
