30. REASONINGThe drawing shows the point between the earth and the moon where the gravitational force exerted on the spacecraft by the earth balances that exerted by the moon. The magnitude of the gravitational force exerted on the spacecraft by the earth is earthspacecraftearth2mmFGr=while that exerted on the spacecraft by the moon is ()moonspacecraftmoon2earth-moonrr=−By setting these two expressions equal to each other (since the gravitational forces balance), we will be able to find the distance
