Question

Which one of the following forces is a contact force? (a) force of gravity (b) magnetic force (c) force of friction (d) electrostatic force​

Answer 1

Answer:

Explanation:Force of friction. C. Magnetic force. D ... So, frictional force is a contact force dependent on surface. Here, option (B) is correct. Gravitational force, electrostatic force and magnetic force does not depend on the surface.

Answer 2

(C) Force of friction is a contact force.

About Force of friction  :

• Because the force of friction occurs through contact between surfaces, it is a contact force among the available alternatives.

• Force of friction is the opposing force formed between two surfaces that are attempting to move in the same direction or in opposite directions.

• A Force of friction's principal purpose is to generate resistance to the mobility of one surface over another.
