If R denotes the radius of orbit of a satellite of mass m revolving around a planet of mass M, the sqiared orbital velocity of the satellite is given by

A

`v_(o)^(2)=(GM)/(R)`

B

`v_(o)^(2)=(GR)/(M)`

C

`v_(o)^(2)=(GmM)/(R)`

D

`v_(o)^(2)=(GM)/(mR)`

Text Solution

Verified by Experts

The correct Answer is:
A
`(mv_(o)^(2))/(R)`=centripetal force `=(gmM)/(R^(2))=` Gravitationa force
`rArr " " v_(o)^(2)=(GM)/(R)`
