The pulley arrangement shown in fig are identical, the mass of the rope being negligible. In case I , the mass m is lifted by attaching a mass 2m to the other end of the rope . in case II , the mass m is lifted by pulling the other end of the rope with constant downward force F = 2 mg ,where g is acceleration due to gravity. The acceleration of mass in case I is
