Question

Which one of the following does not accurately describe the universal gravitational law? A. Gravitational force is proportional to the product of the two masses. B. Gravitational force is proportional to the square of the distance between the centers of both bodies. C. Every object in the universe that has mass attracts every other object in the universe that has mass. D. The object with the smaller mass does most of the moving because the object with the larger mass has too much inertia to move any noticeable amount.

Answer 1

To my knowledge the correct answer is B.

Answer 2

Remark
All the statements are correct except for B

B is wrong because the Force is inversely proportional to the square of the distance.

D is correct. That's what Newton saw when he watched the apple fall. The apple did all the moving.

A is correct. The formula is
F = G*m1*m2/r^2
If r is held constant the formula becomes
F = k * m1 * m2 where k = G/r^2

C is true as well, but it sure decreases in strength because of the distance and the smallness of G.
