A Bob of mass m is attached to a massless string whose other end is connected to the fixed support O Initially string is horizontal and bob is held at rest At t 0 bob is released and it takes time t to reach bottom most position During the given interval of time t R A Average value of tension in string is m g 1 B Average value of tension in string is mg e Magnitude of angular momentum of bob about point O will increase D Average value of torque due to weight of bob about O will be m 2gR R t ox
