Consider a body, shown in figure, consisting of two identical balls, each of mass M connected by a light rigid rod. If an impulse J = MV is imparted to the body at one of its ends what would be it angular velocity?

Consider a system consisting of two identical balls each of mass M connected by a light rigid rod as shown in figure. An impulse J=MV is imparted to the system at one of its ends. The angular velocity of the system would be

Fig. shows a ball having a charge q fixed at a point A. Two identical balls of mass m having charge +q and -q are attaached to the end of a light rod of length 2a. The system is released from the situation shown in fig. Find the angular velocity of the rod when the rod turns through 90^(@)

Figure a rigid body consisting of two particles of mass m connected by a rod of length L and negligible mass. (a) What is the rotational inertia I_(com) about an axis through the center of mass, perpendicular to the rod as shown? (b) What is the rotational inertia I of the body about an axis through the left end of the rod and parallel to the first axis.
