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 the second particle will be

The figure below shows a body of mass $M$ moving with a uniform speed $v$ on a circular path of radius $R$. What is the change in acceleration when moving from point $P_1$ to $P_2$?

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