Two cars of masses `m_(1)` and `m_(2)` are moving in circles of radii `r_(1)`and `r_(2)`, respectively. Their speeds are such that they make complete circles in the same time. The ratio of their centripetal acceleration is :

Options

A. `1:1`
B. `m_(1)r_(1):m_(2)r_(2)`
C. `m_(1):m_(2)`
D. `r_(1):r_(2)`

Answer

D

Explanation

`(a_(1))/(a_(2))=(omega^(2)r_(1))/(omega^(2)r_(2))=(r_(1))/(r_(2))`
Hence choice is (d).
