Question

Quizplus · Accepted Answer

According to the universal law of gravitation, the gravitational force between two objects is inversely proportional to the square of the distance between them. Therefore, if you triple the distance between two objects, the gravitational force will decrease by a factor of 9 (3 squared), which means it will decrease by 9 times. Therefore, the correct choice is E - decrease by a factor of 9.
