A particle moving with uniform speed in a circular path maintains:
Constant acceleration
Constant velocity but varying acceleration
Varying velocity and varying acceleration
Constant velocity
The angular acceleration of a body, moving along the circumference of a circle, is :
A particle revolves round a circular path. The acceleration of the particle is
A particle is revolving in a circular path of radius $25 \,m$ with constant angular speed $12 \,rev/min$. Then the angular acceleration of particle is .......... $rad / s ^2$
In uniform circular motion
The angular speed of a fly wheel making $120$ revolutions/minute is
