उत्तर
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 interchange them i.e. suspend B and bring A near it, again attraction is there. This show that unlike charges attract each other.
-vely charged ebonite rods
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 the second rod near it again the suspended rod moves away showing repulsion between like charges.
