Two particle move in concentio cireles of radii `r_(1)` and `r_(2)` such that they maintain a straight line through the centre. The ratio of their angular veocities is:

Two particle move in concentric circles of radii r_(1) and r_(2) such that they maintain a straight line through the center. The ratio of their angular velocities is:

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

Two cars of masses m_(1)" and" m_(2) are moving in circles od radii r_(1) "and" r_(2) . Their speeds are such that they complete one revolution in the same time. The ratio of their angular speed is :

Two spheres of radii R_(1) and R_(2) are made of the same material and are at the same temperature. The ratio of their thermal capacities is:

Two racing cars having masse m_(1) and m_(2) move in concentric circle of radii r_(1) and r_(2) respectively. If their angular speed are same , then ratio of their linear speed is

Two cars having masses m_1 and m_2 move in circles of radii r_1 and r_2 respectively. If they complete the circle is equal time the ratio of their angular speeds is omega_1/omega_2 is

Two cars having masses m_1 and m_2 move in circles of radii r_1 and r_2 respectively. If they complete the circle is equal time the ratio of their angular speeds is omega_1/omega_2 is
