In the simulation, start with m1=200 kgm1=200 kg and m2=400 kgm2=400 kg with their centers 8 meters apart. If you want to increase in the gravitational force between the two masses by the greatest amount, should you double the mass of m2m2 or should you halve the distance between the masses? In one or two sentences, explain which option would create the greater increase in the gravitational force and why.
