Question

As per the principle of moment of momentum, the resultant external torque about any axis is equal to: *
2 points
Rate of change of momentum about the axis.
Change of moment of momentum about the axis
Change of angular momentum about the axis
Rate of change of angular momentum about the axis.
​

Answer 1

Answer:

4.) Rate of change of angular momentum about the axis

Explanation:

External Torque = Rate of change of angular momentum about the axis

This is the general definition of Torque. It can also be written as:

τ = dL/dt, where τ is torque, L is angular momentum and t is time.
