Quizplus · Accepted Answer

There is no point where there is no more gravitational force exerted on the spaceship by Earth. Gravitational force decreases with distance but never becomes zero, no matter how far the spaceship travels away from Earth. However, the gravitational force from the Moon becomes stronger as the spaceship approaches it.
