The angular momentum of a moving body remains constant if

Question

The angular momentum of a moving body remains constant if (A) net external force is applied (B) net external torque is applied (C) net pressure is applied (D) net external torque is not applied

Tardigrade Admin · Accepted Answer

When the net external torque acting on a system is zero, the total angular momentum of the system remains constant. Therefore the angular momentum of a moving body remains constant if net external torque is not applied.

Q. The angular momentum of a moving body remains constant if

net external force is applied

net external torque is applied

net pressure is applied

net external torque is not applied

When the net external torque acting on a system is zero, the total angular momentum of the system remains constant. Therefore the angular momentum of a moving body remains constant if net external torque is not applied.
