MCQ

Suppose, the acceleration due to gravity at the earth's surface is $10 \mathrm{~ms}^{-2}$ and at the surface of Mars it is $4.0 \mathrm{~ms}^{-2}$. 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 best represents the weight $($net gravitational force$)$ of the passenger as a function of time?

A
$A$
B
$B$
✓
$C$
D
$D$

✓

Answer

Correct option: C.

$C$

At one point between the Earth and Mars, the gravitational field intensity is zero. So, at that point, the weight of the passenger is zero. The curve $C$ indicates that the weight of the passenger is zero at a point between the Earth and Mars.
