The orbital velocity of an artifical sat...

The orbital velocity of an artifical satellite in a circular orbit just above the earth's surface is `V_(0)`. For a satellite orbiting at an altitude of half of earth's radius, the orbital velocity is

A

`3/2v`

B

`sqrt(3/2)v`

C

`sqrt(2/3)v`

D

`2/3v`

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(0)=sqrt((GM)/(R+h))implies(v_(2))/(v_(1))=sqrt(R/(R+h))`
`(v_(2))/(v_(1))=sqrt(2/3)`
