Explanation / Answer

Here ,

acceleration, a = 0.895 rad/s^2

moment of inertia , I = (2/3)*mr^2

I = (2/3)*8.25 * 0.240^2

I = 0.317 Kg.m^2

Now , for the torque applied ,

using second law of motion

T = I*acceleration

T = 0.317 * 0.895

T = 0.284 N.m

the torque acting on the sphere is 0.284 N.m
