Which of the following quantities is directly proportional to the gravitational pull between two objects? sum of their volumes product of their masses distance that separates them distance from their center to their surface

The correct answer is:

Product of their masses

In fact, the gravitational pull between two objects is given by:

where

G is the gravitational constant

m1 and m2 are the masses of the two objects

r is the distance between the centres of the two objects

From the equation, we immediately see that the gravitational attraction is directly proportional to the product of the masses.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
