Imagine a spacecraft going from the earth to the moon. How does its weight vary as it goes from the earth to the moon?                          

Answer:

                (i) As the spacecraft moves from the earth towards the moon, its weight decreases.                 (ii) The weight of the spacecraft becomes zero at the null point where the gravitational forces of the earth and the moon are equal and opposite.                 (iii) Again the weight increases, becoming \[mg/6\]on the moon's surface.
