MHT CET 2026 Physics question
A satellite is revolving around a planet in a circular orbit close to its surface. Let be mean density and R be the radius of the planet; then the period of the satellite is (G = Universal constant of gravitation).
Answer: (D)
Solution
For an orbit close to the surface the orbital radius equals , and the period is . With : , so \sqrt{\dfrac{3}{4π G p}}$ =
