Question

Escape velocity from the surface of moon is less than that from the surface of earth because the moon has no atmosphere while earth has a very dense one.

• A. True
• B. False

Answer 1

The correct option is B False

As escape velocity depends on the acceleration due to gravity. So, escape velocity for moon must be less than that for earth. And due to less escape velocity the gas molecules easily escape from the planet as it become less than $rms$ velocity of gas molecules resulting no atmosphere.
