Question

The escape velocity of a body on earth ________ .

A.

increases with the increase of its mass 

B.

increases with the increase of its mass 

C.

remains unchanged with variation of mass 

D.

varies as the square of the change in mass

Answer ( Option C)

remains unchanged with variation of mass 

Solution

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
