The angular velocity of a particle rotating in a circular orbit $100$ times per minute is
$1.66\, rad/s$
$10.47\, rad/s$
$10.47 \,deg/s$
$60 \,deg/s$
The acceleration vector of a particle in uniform circular motion averaged over the cycle is a null vector. This statement is
For a particle in uniform circular motion, the acceleration $\vec a$ at a point $P(R,\theta)$ on the circle of radius $R$ is (Here $\theta$ is measured from the $x-$ axis)
A motor cyclist going round in a circular track at constant speed has
A wheel is subjected to uniform angular acceleration about its axis. Initially its angular velocity is zero. In the first $2$ sec, it rotates through an angle ${\theta _1}$. In the next $2$ sec, it rotates through an additional angle ${\theta _2}$. The ratio of ${\theta _2}\over{\theta _1}$ is
The average acceleration vector for a particle having a uniform circular motion is
