F=G[(m1)(m2)/r^2], so doubling m2 and r produces a gravitational force of 2/4 or 1/2 of the original force. I think you stated your question incorrectly, since G is the gravitational constant and does not change. Unless, of course, this is a "trick" question. +4

I would think that "g" meaning gravity, would increase exponentially as mass and radius also increases.
