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

`((R _(1) )/(R_(2)))^(2)`

C

`sqrt((R _(1))/(R _(2))`

D

`(R _(1))/(R _(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`(f_(1))/(f_(2))=((mv^(2))/(R_(1)))/((mv^(2))/(R_(2)))=(R_(2))/(R_(1))`
