NEET 2024 Physics Orbital Mechanics MCQ Question
The minimum energy required to launch a satellite of mass m from the surface of earth of mass M and radius R in a circular orbit at an altitude of 2R from the surface of the earth is:
GmM/2R
GmM/3R
5GmM/6R
2GmM/3R
Correct Answer
Detailed Explanation
The total energy required is the sum of the kinetic and potential energy changes. The formula for minimum energy is derived from gravitational potential energy and orbital mechanics.
