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 force is

A

`r_(2)/r_(1)`

B

`sqrt(r_(2)/r_(1))`

C

`(r_(1)/r_(2))^(2)`

D

`(r_(2)/r_(1))^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Since, `F = (mv^(2))/r rArr F prop 1/r rArr F_(1)/F_(2) = r_(2)/r_(1)`
