  • question_answer
    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

    Correct Answer: C

    Solution :

    [c] Initially the weight of the passenger \[=60\times 10=600\text{ }N\] Finally the weight of the passenger \[=60\times 4=240\text{ }N\]and during the flight in between somewhere its weight will be zero because at that point gravitational pull of Earth and Mars will be equal.
