Two particles of same mass are moving with same speed on circular paths of radii r, and \[{{r}_{2}}.\] The ratio of their centripetal forces would be:

A) \[{{r}_{2}}/{{r}_{1}}\]            

B) \[\sqrt{({{r}_{2}}/{{r}_{1}})}\]

C) \[{{({{r}_{2}}/{{r}_{1}})}^{2}}\]                   

D) \[{{({{r}_{1}}/{{r}_{2}})}^{2}}\]
