A body of mass 1 kg is kept on a rough surface having coefficient of friction = 0.25 being pulled by a force of 2N, what will be the value of friction force in N?

(a) 2

(b) 2.5

(c) 0

(d) 4

I got this question in an interview for internship.

The correct answer is (a) 2

To explain: Since the applied force of 2N has a value less than the limiting friction 0.25×9.81

The acting friction will be static having a value of 2N.
