The radii of circular orbits of two satellites \(A\) and \(B\) of the earth are ' \(4 R\) ' and ' \(R\) ' respectively, where \(R\) is the radius of earth. If the speed of satellite \(B\) is 6 V , then the speed of satellite \(A\) will be
- A 3 V
- B 4 V
- C 12 V
- D \(\frac{3}{4} \mathrm{~V}\)
Answer & Solution
Correct Answer
(A) 3 V
Step-by-step Solution
Detailed explanation
\( v \propto \frac{1}{\sqrt{r}} \) \( \frac{v_A}{v_B} = \sqrt{\frac{r_B}{r_A}} \)
