Gravity obeys the inverse square law.This statement implies that the gravitational force of one body on another will be ____ apart.
A) two times stronger at 2 meters than at 6 meters
B) three times stronger at 2 meters than at 6 meters
C) six times weaker at 2 meters than at 6 meters
D) nine times stronger at 2 meters than at 6 meters
E) The brightness of the force will not change with distance between the two bodies.

Question

Quizplus · Accepted Answer

According to the inverse square law, gravitational force is inversely proportional to the square of the distance between two objects. Therefore, if the distance is reduced from 6 meters to 2 meters (a factor of 3), the force becomes 3^2 = 9 times stronger.
