# Suppose, the Acceleration Due to Gravity at the Earth'S Surface is 10 M S−2 and at the Surface of Mars It is 4⋅0 M S−2. a 60 Kg Passenger Goes from the Earth to the Mars - Physics

MCQ

Suppose, the acceleration due to gravity at the earth's surface is 10 m s−2 and at the surface of Mars it is 4⋅0 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 the following figure best represents the weight (net gravitational force) of the passenger as a function of time?

• A

• B

• C

• D

#### Solution

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.

Is there an error in this question or solution?
