Question

How will you show that like charges repel and unlike charges attract each other ?

Solution

Experiment: Take a glass rod rubbed with silk piece (+vely charged) Suspend it in a stand with the help of a thread.
Bring a-vely charged Ebonite rod (rubbed with fur) near the glass rod.

Attraction is seen between the two rods. Now inter change them i.e. suspend B and bring A near it, again attraction is there. This show that unlike charges attract each other.

Now take two glass rods (+vely charged) and bring them near each other, repulsion takes place. Similarly, if we take two -vely charged ebonite rods and suspend one of them and bring second rod near it again the suspended rod moves away showing repulsion between like charges.
