Which one of the following is 'NOT' a contact force? (a) Force of friction. (b) Normal reaction. (c) Gravitational force. (d) Viscous force.

Answer: (c). Friction, normal reaction and viscous force need physical contact between surfaces or with the fluid. Gravitational force acts at a distance through space, without contact. So the answer is (c) gravitational force.
