Q. 35.0( 2 Votes )

Suppose the acceleration due to gravity at the earth’s surface is 10 ms-2 and at the surface of Mars it is4.0 ms-2. A 60 Kg passenger goes from the earth to the Mars in a spaceship moving with a constant velocity. Neglect all other objects in sky. Which part of figure (11-Q1) best represents the weight (net gravitational force) of the passenger as a function of time?

A. A

B. B

C. C

D. D

Answer :

Both Earth and Mars have their own gravitational fields. Hence, there comes a point between them where the object experiences equally gravitational pull from both earth and mars. Hence at that point the total gravitational force is zero. Here, only curve C represents the situation.
