The escape velocity for a rat of mass 1 kg from the earth surface is 11.2 kms−1. The escape velocity for an elephant of mass 6000 kg would be
11.2×102 kms−1
11.2 kms−1
11.2 ×10−2 kms−1
none of these
Escape velocity is independent of mass of object.Ve=2GMR ⇒Ve depends on mass of planet, radius of planet and height of object from the surface of the earth ⇒Ve does not depend on mass of object and angle of projection
