Okay so g on earth is about 9.8

I know that Mass = Density X Volume... so if you double the radius you quarter the "g" ?

What if you double the density and halve the radius.. can you please show me clearly using newtons equation of gravitation what happens to "g" ?

Help is very appreciated!! Thanks in advance!
