Find the torque of a force acting at the point .
The angle between the two vectors will be
A rod of length PQ = l leans by its upper end against a smooth vertical wall while its end leans against the base. The end Q of the rod moves uniformly downward with speed v1. The end P will move on the floor with velocity v2 such that :
v2 is uniform and v2 = v1
v2 is uniform but v2 ≠ v1
v2 continuously increases
v2 continuously decreases
