Question

(7) During dry weather while combing hair, sometimes we experience
hair flying apart. Which force is responsible for this?
A. Gravitational force B. Electrostatic force
C. Frictional force
D. Magnetic force​

Answer 1

Answer:

When two objects are rubbed together, there is exchange of electrons.

During dry weather, the hair follicles are straightened up and they have picked up electrons during the rubbing process. The follicles have the like charges that repel each each other.

The force responsible for this is the electrostatic force.
