A satellite of mass m revolves around the earth of radius R at a hight x from its surface. If g is the acceleration due to gravity on the surface of the earth, the orbital speed of the satellite isA. `gx`B. `(gR)/(R-x)`C. `(gR^(2))/(R-x)`D. `((gR^(2))/(R+x))^(1//2)` |
|
Answer» Correct Answer - D For the satellite, the gravitational force provides the necessary centripetal force, i.e., `(GM_(e)m)/((R+x)^(2))=(mv_(0)^(2))/((R+x))` |
