Two particles of mass M and m are moving in a circle of radii R and r. if their time period are the same, what will be the ratio of their linear velocities?

Two particles having mass M and m are moving in a circular path having radius R and r. If their time period are same then the ratio of angular velocity will be

Two particles having masses M and m are moving in a circular path having radii R and r respectively. If their periods are same, then the ratio of their angular velocities will be

Two particles of masses m_(1) and m_(2) are moving in concentric circle of radii r_(1) and r_(2) such that their period are same. Then the ratio of their centripetal acceleration is

A particle of mass M is revolving along a circule of radius R and nother particle of mass m is recolving in a circle of radius r . If time periods of both particles are same, then the ratio of their angular velocities is
