Two bodies of mass 10 kg and 5 kg are moving in concentric circular orbits of radii ' R ' and ' r ' respectively such that their periods are same. The ratio between their centripetal acceleration is

Step-by-step solution

The centripetal acceleration a for a body in uniform circular motion with orbital radius R and period T is given by a = 4 ^2 R T^2 . Since both bodies have the same period T , the ratio of accelerations a₁ a₂ = R₁ R₂ = R r . Final Answer: A
