A rod not toching the flor is inserted between two identical boxes (see figure) There is a very small gap between the rod and and boxes ,A horizontal force F is applied at the upper end of the rod There is frication between boxes and the floor Assume that the od remains almost vertical after the force is applied which of hte following is /are correct?

A uniform rod of mass M and length L is hinged at its lower end on a table. The rod can rotate freely in vertical plane and there is no friction at the hinge. A ball of mass M and radius R = (L)/(3) is placed in contact with the vertical rod and a horizontal force F is applied at the upper end of the rod. (a) Find the acceleration of the ball immediately after the force starts acting. (b) Find the horizontal component of hinge force acting on the rod immediately after force F starts acting.

A horizontal force F pulls a 20 kg box at a constant speed along a rough horizotal floor. The coefficient of friction between the box and the floor is 0.25. The work done by force F on the block in displacing it by 2 m is

A horizontal force F pulls a 20 kg box at a constant speed along a horizontal floor. If the coefficient of friction between the box and the floor is 0.25,how much work is done by the force F in moving the box through a distance of 2 m?

A massless rod of length l is hinged at one end and is held horizontal by two identical vertical wires, which are tied at distances a and b form the hinged end. A load P si applied at the free end of the rod. The tension in the first is

A massless rod of length l is hinged at one end and is held horizontal by two identical vertical wires, which are tied at distances a and b form the hinged end. A load P si applied at the free end of the rod. The tension in the secound wire is

A boy of mass M is applying a horizontal force to slide a box of mass M' on a rough horizontal force to slide coefficient of friction between the shoes of the boy and the floor is mu and that between the box and the floor is mu' . In which of the following cases it is certainly not possible to slide the box?

A rod of mass m and length L is hinged at its top end. If the rod is in equilibrium making an angle of 30^(@) with the vertical when a horizontal force F is applied as shown in figure, then the value of F is:
