Two bodies of masses 10 kg and 5 kg moving on concentric orbits of radii R and r such that their period of revolution are same. The ratio of their centripetal acceleration is :
R/r
r/R
R²/r²
r²/R²

Solution:

As time period of revolution is same for both the particles angular speed will be equal for both.

Centripetal Acceleration is given by ω²r.

so a 1 / a 2 = R/r
