Motion in A Plane

Question: Two bodies of equal masses revolve in circular orbits of radii \[{R_1}\] and \[{R_2}\] with the same period. Their centripetal forces are in the ratio

1) \[{\left( {\frac{{{R_2}}}{{{R_1}}}} \right)^2}\]

2) \[\frac{{{R_1}}}{{{R_2}}}\]

3) \[{\left( {\frac{{{R_1}}}{{{R_2}}}} \right)^2}\]

4) \[\sqrt {{R_1}{R_2}} \]
