Q152 / 180 · AIIMS 2011 · Physics
Assertion: Total energy is conserved in moving a satellite to higher orbit.
Reason : Sum of change in PE and KE is same in magnitude and opposite in nature.
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- Correct answerCIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Solution
Total energy is given by
$$
E=-\frac{G M m}{2 R}
$$
where $R$ is the radius of orbit.
Hence, the correct answer is option: 'C'.
