A satellite of mass m is orbiting the earth (of radius R) at a height h from its surface. The total energy of the satellite in terms of go, the value of acceleration due to gravity at the earth's surface, is :
Answer & explanation
Correct answer: option 2
Energy : E = - \(\frac{GMm}{2r}\)
r = R + h ; GM = goR2
E = - \(\frac{mg_oR^2}{2(R+h)}\)
