The velocity with which a projectile must be fired so that it escapes earth's gravitation, does not depend on :

A

mass of the earth

B

radius of the projectile orbit

C

mass of the projectile

D

gravitational constant.

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(e )=sqrt((2GM)/(R ))` .
It is independent of the mass of the body to be escaped.
Thus correct choice is (c ).
