Two particles rest at a distance d apart on the edge of a table. One of the particles of mass m, falls off the edge and falls vertically. Using the other particle (still at rest) as the origin, (a) calculate the torque ? on m as a function of time (before hitting the ground below) d b l ) and (b) the angular momentum of the system. th l t f th t (c) Show that ? = dl/dt?
