List of top Physics Questions on Gravitation asked in KCET

Suppose the acceleration due to gravity at the earth's surface is g m/s\(^2\) and at the surface of moon it is g' m/s\(^2\). An M kg passenger goes from the earth to the moon in a spaceship moving with a constant velocity (Neglect all other objects in the sky). Which curve best represents the weight (net gravitational force) as a function of time?
Imagine a new planet having the same density as that of the earth, but it is two times bigger than the earth in size. If the acceleration due to gravity on the surface of the new planet is g' and that on the surface of the earth is g, then
