$A$ particle revolves around a circular path. The acceleration of the particle is

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

Two cars of masses $m_1$ and $m_2$ are moving along circular paths of radii $r_1$ and $r_2$ respectively. Their speeds are such that they complete one round in the same time. The ratio of the angular speeds of the two cars is:

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 is moving in a horizontal circle with constant speed. It has constant

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
