Rotational kinetic energy \(K\) versus angular displacement \(\theta\) for the turntable.
Rotational kinetic energy \(K\) versus angular displacement \(\theta\) for the turntable.
A horizontal turntable rotates about a fixed vertical axis passing through its center with negligible friction. A constant net torque is exerted on the turntable as it rotates. The graph shows the rotational kinetic energy \(K\) of the turntable as a function of its angular displacement \(\theta\). What is the magnitude of the net torque exerted on the turntable?
