The escape velocity of a body on earth
________ .
increases with the increase of its
mass
increases with the increase of its
mass
remains unchanged with variation of
mass
varies as the square of the change in
mass
remains unchanged with variation of
mass
The escape velocity is given by,
Where, G = Gravitational constant
= 6.67 X 10-11 m3 /kgs2
ME= Mass of the earth
RE = Distance from the center of mass of earth body
Thus
we can say that the escape velocity of a body on earth will remain unchanged
with variation of mass.
Hence, the correct option is (C).
&Key Points:-
The
escape velocity of earth is about 11.2 km/s and that of moon and sun is 2.38
km/s and 617.5 km/s respectively
