A satellite revolving around a planet has orbital velocity \(10 \mathrm{~km} / \mathrm{s}\). The additional velocity required for the satellite to escape from the gravitational field of the planet is
- A \(14.14\ km/s\)
- B \(11.2\ km/s\)
- C \(4.14\ km/s\)
- D \(41.4\ km/s\)
Answer & Solution
Correct Answer
(C) \(4.14\ km/s\)
Step-by-step Solution
Detailed explanation
The relation between two velocities is given by the relation \(\begin{aligned} & v_{\mathrm{e}}=(\sqrt{2}-1) v_0 \\ & =(1.414-1) \mathrm{v}_0 \\ & =0.414 \times 10=4.14 \mathrm{~km} / \mathrm{s} \end{aligned}\)
