Vedclass · Answer

(B) The forces acting on the spaceship are the gravitational pull due to the Earth and the gravitational pull due to the Moon.Since the mass of the Earth $(M_E)$ is significantly greater than the mass of the Moon $(M_M)$,the gravitational potential energy and the gravitational force at the Earth's surface are much higher than at the Moon's surface.To escape the Earth's gravitational influence,the spaceship must overcome a much larger gravitational potential barrier compared to the Moon.Therefore,the greatest energy is required to perform a take-off from the Earth's gravitational field.

$A$ spaceship moves from the Earth to the Moon and back. The greatest energy required for the spaceship is to overcome the difficulty in:
