The orbital velocity of an satellite in ...

The orbital velocity of an satellite in a circular orbit just above the earth's surface is `v`. For a satellite orbiting at an altitude of half of the earth's radius, the orbital velocity is

A

`sqrt7v`

B

`v//sqrt7`

C

`sqrt6v`

D

`v//sqrt6`

Text Solution

Verified by Experts

The correct Answer is:
a
`(V_(C_(2)))/(V_(C_(1)))=sqrt((r_(1))/(r_(2)))=sqrt((R)/(R+6R))=sqrt((R)/(7R))`
`V_(C_(2))=(v)/(sqrt7).`
