A constant torque acting on a uniform circular wheel changes its angular momentum from

{A_0}\,\,to\,\,\mathrm{ }7{A_0}

in 3 s. The magnitude of average torque is

View answer and explanation

Correct option: D

2{A_0}

Option D (

2{A_0}

) is correct because the average torque is equal to the rate of change of angular momentum, which is (7A0 - A0)/3 = 2A0.
