A 0.7-kg ball connected to a fixed point by a taut string whirls around a circular path of radius 0.2 m at a speed of 4 m/s. Find the angular momentum of the orbiting ball. (Answer in J * S) Compare this with the intrinsic angular momentum of an electron. How many times larger is the former than the latter?
