Question

A uniform rod of length L and mass M has been placed on a rough horizontal surface. The horizontal force F applied on the rod is such that the rod is just in the state of rest. If the coefficient of friction varies according to the relation m = Kx where K is a +ve constant. Then the tension at mid point of rod is

F/2
F/4
F/8
None

The correct answer is: F/4
