Question

6. During dry weather while combing hair,
sometimes we experience hair flying apart.
The force responsible for this is
(a) force of gravity
(b) electrostatic force
(c) force of friction
(d) magnetic force​

Answer 1

The electrostatic force is responsible for this.

• In the dry weather, the electron transfer between comb and the dry hair, takes place.
• The electrons travels from the dry hair to the comb.
• In this way, the hairs become positively charged and the comb become negatively charged.
• And, we know that are negatively charged object and a positively charged object, attract each other.
• This attraction is popularly termed as the electrostatic force.
