A man can move on a horizontal plank supported symmetrically as shown. The variation of normal reaction on support A with distance x of the man from the end of the plank is best represented by :

A man of mass M stands at one end of a plank of length L Which lies at rest on a frictionless surface . The man walks to the other end of the plank. If the mass of the plank is 3M, the distance that the man moves relative to the ground is

A man of mass M stands at one end of a plank of length L Which lies at rest on a frictionless surface . The man walks to the other end of the plank. If the mass of the plank is 3M, the distance that the man moves relative to the ground is

A plank of mass M is placed on a rough horizontal force F is applied on it A man of mass m rens on the plank find the acceleration of the man so that the plank does not move on the surface . The coefficent of friction between the plank and the surface is mu Assume that the man does not slip on the plank

A man of mass M stands at one end of a plank of length L which lies at rest on a frictionless surface. The man walks to the other end of the planck. If the mass of the planck is M/2 , then the distance that the man moves relative to the ground is

A man of mass m moves with a constant speed on a plank of mass M and length l kept initially at rest on a frictionless horizontal surface, from one end to the other in time t. The speed of the plank relative to grounud while man is moving, is
