Two satellite of masses `400 kg,500kg` are revolving around earth in different circular orbits of radii `r_(1),r_(2)` such that their kinetic energies are equal. The ratio of `r_(1)` to `r_(2)` is

A

`sqrt(5):sqrt(4)`

B

`16:25`

C

`sqrt(4):sqrt(5)`

D

`25:16`

Text Solution

Verified by Experts

The correct Answer is:
A
`KE_(1)=KE_(2), L=mvr` and `(r_(1))/(r_(2))=(sqrt(m_(2)))/(sqrt(m_(1)))`
