MP Board · Class 11 · Physics · GravitationTotal mechanical energy of a satellite of mass $m$ revolving close to Earth's surface in a circular orbit of radius $R$ is:
Step-by-Step Solution
Kinetic Energy $K = \frac{GMm}{2R}$ and Potential Energy $U = -\frac{GMm}{R}$. Total Energy $E = K + U = -\frac{GMm}{2R}$.
