MCQ

Suppose, the acceleration due to gravity at the earth's surface is $10ms^{-2}$ and at the surface of Mars it is $4⋅0ms^{-2}$. A 60kg 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

C

Explanation:

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.
