railway RRB JE (CBT I + CBT II) Mock Test 2024 Engineering Mechanics Equilibrium and Friction Friction
A body weighing 200 N is resting on a rough horizontal surface. A pull of 100 N applied at an angle of 30° with horizontal just causes the body to slide over the surface. What will be the coefficient of friction between the body and the surface?
