Question

Describe an activity that gives an understanding of ‘Electrostatic force’. OR Describe an activity that gives an understanding of‘Electroplating’.

Answer 1

Answer:

Rub a comb through your dry hair(not oiled hair) for some time. When the comb is rubbed in your dry hair, it acquires a property called electrostatic charge. Electrostatic charge can exert a force called electrostatic force. It is because of this force that the bits of paper get attracted to your comb.
