If the escape velocity on earth is \(11.2 \mathrm{~km} / \mathrm{s}\), its value for a planet having double the radius and 8 time the mass of earth is
- A 22.4 km/s
- B 24.3 km/s
- C 26.6 km/s
- D 44.8 km/s
Answer & Solution
Correct Answer
(A) 22.4 km/s
Step-by-step Solution
Detailed explanation
Escape velocity of an object on a planetary body, \(v_e=\sqrt{\frac{2 G M}{R}} \Rightarrow v_e \propto \sqrt{\frac{M}{R}}\) So,…
