Explanation:
Detailed explanation-1: -The escape velocity of a body on the surface of the earth is 11.2 km/s. If the earth’s mass increases to twice its present value and radius of the earth becomes half, the escape velocity from the new surface becomes. No worries!
Detailed explanation-2: -M= mass of the planet; R = radius of the planet. So to find the escape velocity for our planet. We already know that the escape velocity of earth is 11.2km/sec. The escape velocity of our new planet will be 22.4 km/sec.
