Solution
Correct Answer:
r3
Kepler's Law of Periods (3rd Law) states: 'The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis (radius for a circle) of its orbit.' T2∝r3
- Derived by equating r2GMm=m(T2π)2r⟹T2=GM4π2r3.
This medium difficulty physics question is from the chapter gravitation, covering the topic of kepler's third law. It appeared in the 2025 exam.
