If the escape velocity on the earth is 11.2 Km/s, its value for a planet having double the radius and 8 times the mass of the earth is …… (in km/s)

View answer and explanation

Correct option: B

22.4

Option B (22.4) is correct because the escape velocity is proportional to the square root of (M/R).
