as we know angular momentam associated with a body is given by
L(angular momentam) =Iw
if w is changing with time it means there is a torque which is responsble for this change..
L=Iw
dL/dt =d(Iw)/dt (rate of change of angularmomentam)
dL/dt=Idw/dt
dw/dt =@ (angular accleration)
dL/dt=T(torque) = I@ .................

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
