Question
Suppose the gravity of the earth suddenly becomes zero, then in which direction will the moon begin to move if no other celestial body affects it?

Solution
The circular motion of the moon around the earth is due to the centripetal force provided by the gravitational force of the earth. Therefore,
when the gravity of the earth suddenly becomes zero, the moon will begin to move in a straight line in the direction in which it was moving at that instant. That is the moon will move along the tangent to the circular orbit at that instant.
