The angular momentum of a rotating body changes from `A_(0)` to `4 A_(0)` in 4 min. The torque acting on the body is

Under a constant torque, the angular momentum of a body changes from 2x to 5x in 8 sec. The torque acting on the body is

Under a constant torque, the angular momentum of a body changes from A to 4 A in 4 sec The torque on the body will be

Torque acting on a rotating body

If there a change in the angular momentum of a body from "5 kg-m"^(2)//s to "8 kg-m"^(2)//s in 4 seconds, then the torque acting on the body is

Total angular momentum of a rotating body remains constant, if the net torque acting on the body is

Total angular momentum of a rotating body remains constant, if the net torque acting on the body is

The angular momentum of a rotating body is doubled, its K.E. of rotation becomes
