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
- \(g x\)
- \(\frac{g R}{R-x}\)
- \(\frac{\mathrm{gR}^{2}}{\mathrm{R}+\mathrm{x}}\)
- \(\left(\frac{g R^{2}}{R+x}\right)^{\frac{1}{2}}\)
Answer
(D) ( g R^ 2 R+x )^ 1 2
