Derive an expression for orbital velocity of the satellite.

Text Solution

Verified by Experts

For a satellite of mass M to move in a circular orbit, centripetal force must be acting on the satellite. This centripetal force is provided by the Earth's gravitational force.
`(Mv^2)/((R_(E)+h))=(GMM_E)/((R_(E)+h)^(2))`
`v^(2)=(GM_E)/((R_(E)+h))`
`v=sqrt((GM_E)/((R_(E)+h)))`
