Suppose, the acceleration due to gravity at the Earth's surface is \[10\text{ }m\text{ }{{s}^{-2}}\] and at the surface of Mars is \[4\text{ }m\text{ }{{s}^{-2}}\]. A 60 kg passenger goes from the Earth to the Mars in a spaceship moving with a constant velocity. Neglect all other objects in the sky. Which part of figure best represents the weight (net gravitational force) of the passenger as a function of time?
