Motion in A Plane

Question: Two particles of equal masses are revolving in circular paths of radii \[{r_1}\] and \[{r_2}\] respectively with the same speed. The ratio of their centripetal forces is

1) \[\frac{{{r_2}}}{{{r_1}}}\]

2) \[\sqrt {\frac{{{r_2}}}{{{r_1}}}} \]

3) \[{\left( {\frac{{{r_1}}}{{{r_2}}}} \right)^2}\]

4) \[{\left( {\frac{{{r_2}}}{{{r_1}}}} \right)^2}\]
