Question

The Escape velocity from the Earth for a body of mass 100 g is 11.2 km/s. What will be its value for a body of 20 g? Justify.​

Answer 1

Answer:

Escape velocity is independent of the mass of the projected body provided the air resistance is neglected. Hence, the escape velocity of 10kg10kg of the iron ball projected from the earth is same that of escape velocity of 10g10g projected from the earth i.e., 11.2kms−1
