----------------------------------------------------
as mass is unaffected by gravity the escape velocity is same for all

Answer 2

The formula of escape velocity is independent of the mass of the body. Escape velocity is same for all bodies in the same planet irrespective of the individual masses. The escape velocity depends on radius and mass of the planet.
