A person whose mass is 100 kg travels from Earth to Mars in a spaceship. Neglect all other objects in sky and take acceleration due to gravity on the
surface of the Earth and Mars as 10 m s-2 and 4 m s-2, respectively. Identify from the below figures, the curve that fits best for the weight of the passenger as a function of time.

Options:

Answer:
A
Solution:

When the passenger moves away from the Earth at some point, gravitational force due to earth will be minimised and then start increasing as the passenger moves towards Mars as g∝1R2 also gravitational force cannot be negative. Therefore, the correct curve that fits best for the weight of the passenger as a function of time is c.
