The force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. (correct)

The force of attraction between two objects is inversely proportional to the sum of their masses and directly proportional to the distance between them.

The force of attraction between two objects is directly proportional to the sum of their masses and inversely proportional to the distance between them.

The force of attraction between two objects is directly proportional to the square of the distance between them and inversely proportional to the product of their masses.

F = (m1 * m2) / (G * r^2)

F = (m1 * r^2) / (G * m2)

F = (G * m1 * m2) / r^2 (correct)

F = G * (m1 / r^2) * m2
