Define angular acceleration.

The moment of inertia of flywheel is 4 kg m^2 . If a torque of 10 Nm is applied on it, then the angular acceleration produced will be

The frequency of a particle performing circular motion changes from 60 rpm to 180 rpm in 20 s. Then the angular acceleration is

If an electric fan revolving at 600 rpm isspeeded up uniformly to 1200 rpm in 4 s, then the angular acceleration of the fan will be

If a body is moving with a uniform speed v in a circle of radius r , then the angular acceleration of the body will be

A rope is wound round a hollow cylinder of mass M and radiusR. If the rope is pulled with a force F newton, then the angular acceleration of the cylinder will be

A flywheel revolves at 100 rev/min, a torque is applied to the flywheel for 10 s if thetorque increases the speed to 200 rev/min, then the angular acceleration of the flywheel will be

A fly wheel revolves at 100 rev//min , a torque is applied to the flywheel for 10s. If the torque increases the speed to 200 rev//min , then the angular acceleration of the fly wheel will be

The angle turned by a body undergoing circular motion depends on time as theta = theta_(0)+theta_(1)t+theta_(2)t^(2) . Then the angular acceleration of the body is

The speed of abody moving along a circle of radius 15 cm changes from 180 rev/min to 600 rev/min in 11 s. Then the angular acceleration of the body will be

A body moves with constant angular velocity on a circle. Magnitude of angular acceleration
