Using the gravitational force formula, if the distance is tripled the force between them will decrease by nine times since F= ( G * m1 *m2 ) / R² where R is the distance between two bodies.  Neglecting the masses which arent given, 3² is 9 and they are inversely proportional to the gravitational force.
