A body of mass 1 kg rests on a horizontal floor with which it has a coefficient of static friction μs = 1√3. It is desired to make the body move by applying the minimum possible force F (in Newtons). Find the value of F. [Take g = 10 ms-2]

The magnitude and direction of the acceleration produced in a body of mass 5 kg when two mutually perpendicular forces 8 N and 6 N act on it, are respectively:

Two blocks of masses 3 kg and 1 kg are placed in contact on a smooth horizontal surface. A horizontal force F = 5 N is applied on the 3 kg block from the left. Find the contact force exerted between the two bodies.
