here is the answer hope it works

Answer 2

Answer:

(a) Frictional force:- Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

(b) Electrostatic force:- Electrostatic force is the force exerted by a charged body on another charged or uncharged body. ... This is because the comb is charged because of the rubbing on your hair and it attracts uncharged objects like paper.

(c) Gravitational force:- Gravitational force is a force exerted by the earth on all objects on it. When a ball is thrown up, it falls to the ground because of gravitational force. The water from a tap always flows downwards because of gravitational force.
