Question

A satellite of mass m is orbiting the Earth at a height h above its surface. The mass of the Earth is M and its radius R . Match the physical quantities in List-II with the expression in List-I. List - I List - II (P) 2 ( R + h ) GM m ​ (1) Potential energy of the earth satellite system (Q) R + h GM ​ ​ (2) Kinetic energy of the satellite (R) R + h − GM m ​ (3) Orbital velocity of the satellite (S) 2 ( R + h ) − GM m ​ (4) Total energy of satellite (5) None of these

TestHub · Accepted Answer

Potential energy = − R + h GM m ​ ⇒ R → 1. Kinetic energy = + 2 ( R + h ) GM m ​ ⇒ P → 2. Orbital velocity = R + h GM ​ ​ ⇒ Q → 3. Total energy = − 2 ( R + h ) GM m ​ ⇒ S → 4. Ans (A).
