The critical velocity of a satellite revolving around the Earth is 10 km/s at a height where gh = 8 m/s^2.
Given: vc = 10 km/s = 10 × 103 m/s, gh = 8 m/s3, R = 6.4 × 106 m To find: Height of the satellite (h) Formula: vc = \(\sqrt{g_h(R+h)}\) Calculation: From formula, 10 × 103 = \(\sqrt{8\times(R+h)}\) Squaring both the sides,...

Time period of revolution of a satellite around a planet of radius R is T. Period of revolution around another planet whose radius is 3R is
Correct option is: (A) T Period of resolution \(T = 2 \pi \sqrt \frac{R^3}{GM} \) \(T = 2 \pi \sqrt \frac{R^3}{G \frac{4}{3} \pi R^3 \rho} \) The period of revolution depends upon the density of...
