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

Option C, The square of the distance that separates them

Explanation:

The formula for gravitational pull between two objects is given by

Where

G = gravitational constant

m1 and m2 is the mass of the two objects

and r is the distance between the two objects

Thus, as visible from the equation,

Gravitational force "F" is directly proportional to mass of the bodies and inversely proportional to the square of the distance that separates them

Thus, option C is correct.
