Suppose the acceleration due to gravity at earth's surface is `10ms^-2` and at the surface of Mars it is `4.0ms^-2`. A passenger goes from the to the mars in a spaceship with a constant velocity. Neglect all other object in sky. Which part of figure best represent the weight (net gravitational force) of the passenger as a function of time?

Options

A. `A`
B. `B`
C. `C`
D. `D`

Answer

C

Explanation

`g_(e)=10m//s^(2),g_(m)=4m//s^(2)`
`W_(e)=60 ,g_(e)=600 N,W_(m)=60, g_(m)=240 N`
From going from earth to mars, at some place, gravitational pull by earth gravitational pull by mars i.e. net weight becomes zero.
