The larger the mass between two planets the gravitational force between them Fg = Gm1m2/r^2

Options :

-larger
-smaller
-no change

The larger the mass between two planets the GREATER gravitational force between them

Explanation

Your equation shows that the force Fg is the product of the gravitation constant G and the two masses, m1 and m2 over the square of the distance between them.

If the distance does not change and G is constant, then an increase in either m1 or m2 (or both of them) will result in a GREATER gravitational force.
