The ratio of the angular velocity of the hour hand of a watch to the angular velocity of the rotation of the Earth is:

$A$ particle is moving on a circular path with constant speed $v$. It moves between two points $A$ and $B$,which subtend an angle $60^{\circ}$ at the centre of the circle. The magnitude of the change in its velocity and the change in the magnitude of its velocity during motion from $A$ to $B$ are respectively ..........

What is the direction of instantaneous velocity for an angular path?

"$A$ particle moving with constant speed on a circle about a fixed axis has a constant angular velocity,but its linear velocity is not constant." Is this possible? Why?

$A$ body moves along a circular path of radius $15 \ cm$. It starts from a point on the circular path and reaches the end of the diameter in $3 \ s$. The angular speed of the body in $rad/s$ is

If the speed $(v)$ and radius $(r)$ of a particle performing uniform circular motion are both doubled,find its new centripetal acceleration.
