A satellite of mass m revolves around the earth of radius R at a height x from its surface. If g is the acceleration due to gravity on the surface of the earth, the orbital speed of the satellite is:

A

gX

B

`((gR^(2))/(R+X))^(1//2)`

C

`(gR^(2))/(R+X)`

D

`(gR)/(R-X)`

Text Solution

Verified by Experts

The correct Answer is:
B
`v_(0)=sqrt((GM)/(R+x))=sqrt((gR^(2))/(R+x))`
Thus correct choice is (b).
