Figure shows a cylinder containing helium gas at atmospheric pressure

1.	Figure shows a cylinder containing helium gas at atmospheric pressure with a tightly fitting piston of weight, one fourth the force acting due to atmospheric pressure. The cylinder is jammed at its bottom. A block B is hung by means of a massless string whose other end is attached to the piston. It is observed that the piston just starts sliding. next, the block B is directly placed above the piston. Assuming the piston to move slowly, find the fractional volume of the gas compressed
