5.An elephant and an ant are to be projected out of the earth into space. What is the velocity needed to do so?
A.Elephant needs to be projected with a higher velocity
B.Ant should be projected with a higher velocity
C.Both should be projected with the same velocity
D.Elephant cannot be projected to space
Answer:  Option  C
Explanation:

The escape velocity ve=√2gR, does not depend upon the mass of the projected body. Thus we need the same velocity to project an elephant and an ant into space.
