Two satellites P and Q go round a planet in circular orbits having radii ' \(3 R\) ' and ' \(R\) ' respectively. If the speed of satellite \(P\) is ' \(2 V\) ', the speed of the satellite Q will be
- A \(2 \sqrt{3} V\)
- B \(\frac{2 \mathrm{~V}}{\sqrt{3}}\)
- C \(\frac{\mathrm{V}}{2}\)
- D \(\frac{\mathrm{V}}{\sqrt{3}}\)
Answer & Solution
Correct Answer
(A) \(2 \sqrt{3} V\)
Step-by-step Solution
Detailed explanation
\( v \propto \frac{1}{\sqrt{r}} \) \( v_Q = v_P \sqrt{\frac{r_P}{r_Q}} \)
