The ratio of the angular speed of the hour hand of a clock to the angular speed of the minute hand is .......

An object moves at a constant speed along a circular path in a horizontal plane with its centre at the origin. When the object is at $x = +2\,m$,its velocity is $-4 \hat{j}\,m/s$. The object's velocity $(v)$ and acceleration $(a)$ at $x = -2\,m$ will be

When a particle moves in a uniform circular motion,it has:

How much work is done by the centripetal force on an object moving in uniform circular motion?

$A$ body of mass $m$ moves in a circular path with uniform angular velocity. The motion of the body has constant

Assertion $(A)$ :- If a body is in a state of uniform circular motion,then its velocity and acceleration both are varying.
Reason $(R)$ :- If the magnitude of velocity is $v$ and the radius of uniform circular motion is $r$,then the magnitude of acceleration is $v^2/r$.
