A person whose mass is 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 and , respectively. Identify from the below figures, the curve that fits best for the weight of the passenger as a function of time.
Options
- A
- B
- C
- D
Correct answer
A.
Step-by-step 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 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 .
