Two particles having mass $M$ and $m$ are moving in a circular path with radius $R$ and $r$ respectively. The time period for both the particles is same. The ratio of angular velocity of the first particle to that of the second particle will be

$A$ particle moves in the $x-y$ plane according to the rules $x = a \sin \omega t$ and $y = a \cos \omega t$. The particle follows:

The angular speed of a flywheel making $120$ revolutions per minute is:

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

$A$ body performing uniform circular motion of radius $R$ has frequency $n$. Its centripetal acceleration is

$A$ ball is moving uniformly in a circular path of radius $1 \, m$ with a time period of $1.5 \, s$. If the ball is suddenly stopped at $t = 8.3 \, s$,the magnitude of the displacement of the ball with respect to its position at $t = 0 \, s$ is closest to .......... $m$.
