Solution

Positive and negative charges
Objects can be positively charged, negatively charged or neutral (no charge).

A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged.

When a charged object comes near to another object they will either attract or repel each other.

If the charges are the same - they repel

If the charges are opposite - they attract

If one is charged and the other is not - they attract
