Suppose, the acceleration due to gravity at the Earth's surface is 10 m `s^(-2)` and at the surface of Mars is 4 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?

Text Solution

Verified by Experts

The correct Answer is:
C
Weight of passenger on Earth `= m xx g_(e ) = 60 xx 10 = 600` N
Weight of passenger on Mars `= mxxg_(m) = 60 xx 4 = 240` N
As the passenger is going from the Earth to the Mars in a spaceship moving with a constant velocity so the acceleration due to gravity because of Earth and Mars becomes negligible (zero) at some point in space. Thus, weight of passenger becomes zero.
After sometime, as he reaches near to the Mars, his weight increases because of acceleration due to gravity of Mars. Finally, at the surface of Mars, his weight becomes 240 N.
