Questions
A body of mass m is kept on a rough horizontal surface (coefficient of friction = ). A horizontal force is applied on the body, but it does not move. The resultant of normal reaction and the frictional force acting on the object is given by F, where F is,
detailed solution
Correct option is D
Since body does not move hence it is in equilibrium.fr = frictional force which is less than or equal to limiting friction.Now N = mg Hence F→=N→+f→r |F→|≤(mg)2+(μmg)2 |F→|≤mg1+μ2Talk to our academic expert!
