Question
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
Options
A.gx
B.

C.

D.

Solution
For the satellite, the gravitational force provides the necessary centripetal force i.e.
and
= g
∴ v0 =
and
= g∴ v0 =
