Question

What happens if two objects having same charge brought close to each other? What happens if two objects having different charges are brought close? Can you give an example for this.

Answer 1

Two objects having same charge repel each other and two objects having different charge attract each other. E.g. A balloon rubbed with woollen cloth repelled by another balloon rubbed with woollen cloth because both will acquire same type of charge. A balloon rubbed with a woollen cloth attracted by a refill rubbed with a polythene sheet because both will acquire different type of charge.
