the hand is not exerting a force, the hand is countering the force because of the force exerted by the mass, the hand initially exerts a force (because we are assuming that the body is always in equilibrium) and this is countered by the force exerted by the mass. As the mass drops, it requires progressively lesser support from the hand and finally when the body has dropped, the support required from the hand is zero. At every point the force exerted by the mass is balanced by supporting force from the hand. (while the motion takes place, the force because of the mass is infinitesimally higher than the supporting force and hence the downward motion)Doc Al said:What's the direction of the force exerted by the hand? What's the direction of motion?
