A block is pulled slowly as shown in the diagram. Show that force `F` increase as the block moves up. Find the force `F` when the block is at depth `h`.

What is the maximum value of the force F such that the block shown in the figure does not move?

What is the maximum value of the force F such that the block shown in the figure does not move?

A block of mass m is connected to another block of mass M by a spring (massless) of spring constant k. The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unstretched. Then a constant force F starts acting on the block of mass M to pull it. Find the force on the block of mass m

A block of mass 1 kg is pulled slowly along the curve path ACB by a tangential force as shown in figure. The magnitude of work done by the frictional force when the block moves from A to B is
