(A) Magnetic force

(B) Electrostatic force

(C) Gravitational force

(D) Frictional force

The frictional force is an example of contact force. The force produced when two surfaces come into contact and slide against one another is referred to as friction force. A contact force is any force that requires contact to happen.

### Explain Contact Force

The most obvious interactions of matter collections across microscopes are caused by contact forces, which are ubiquitous and pervasive.

• The normal force perpendicular to the contact surface(s) and the force of friction parallel to the contact surface are two orthogonal components of contact forces that are frequently separated (s).
• One of the four fundamental forces of nature, the magnetic force, is a result of the electromagnetic force and is brought about by the movement of charges.
• Due to their electric charge, particles or objects are attracted to or repelled by the electrostatic force.
• The planet's gravitational pull is equivalent to the pull the planet has on you.

F = G m1m2/r2, where, F = Force, G = Gravitational constant, m1 = Mass of object 1, m2 = Mass of object 2, r = distance between centers of the masses.

Summary:

## Which of the following is an example of contact force? (A) Magnetic force (B) Electrostatic force (C) Gravitational force (D) Frictional force.

One type of contact force is the frictional force. It is the force which is produced when two surfaces slide against each other. Contact force is defined as the force that requires contact with another object to act.
