Two satellite revolve around the earth in circular orbits at heights `h_(1) and h_(2)` above the surface of the earth respectively. If R is radius of the earth, then the ratio of their orbital linear velocities is

A

`sqrt((R+h_(1))/(R+h_(2)))`

B

`sqrt((R+h_(2))/(R+h_(1)))`

C

`sqrt((h_(1))/(h_(2)))`

D

`sqrt((h_(2))/(h_(1)))`

Text Solution

Verified by Experts

The correct Answer is:
b
`(V_(C_(1)))/(V_(C_(2)))=sqrt((r_(2))/(r_(1)))=sqrt((R+h_(2))/(R+h_(1)))`
