Question

angular movement of a moving body remains constant if
1) net external force is applied
2) net external torque is not applied
3) net pressure is applied
4) net external torque is applied how many Mev are their in 1 kilo watt - houe​

Answer 1

Answer:

angular movement of a moving body remains constant if :-

• net external torque is applied.

Answer 2

Answer:

2) when net external torque is not applied

Explanation:

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.
