Suppose, the acceleration due to gravity at the Earth's surface is \[10\,m{{s}^{2}}\] and at the surface of Mars it is \[4.0\,m/{{s}^{2}}\].\[A\,60-kg\] 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?

• A. A                     
• B. B
• C. C        
• D. D
