Choose the correct statement.
- A Acceleration due to gravity increases with increasing altitude.
- B Acceleration due to gravity is independent of mass of earth.
- C A geostationary satellite can have a time period less than 24 h.
- D Acceleration due to gravity decreases with increasing depth assuming earth to be a sphere of uniform density.
Answer & Solution
Correct Answer
(D) Acceleration due to gravity decreases with increasing depth assuming earth to be a sphere of uniform density.
Step-by-step Solution
Detailed explanation
Acceleration due to gravity at altitude \(h\) is \(g_h=\frac{G M}{(R+h)^2}\) \(\therefore g_h\) decreases with altitude. \(g=\frac{G M}{R^2}, g \propto M\) Geostationary satellite has a time period of \(24 \mathrm{~h}\). \(g\) at depth \(d\) is…
