Thanks for the replies.
Not done the calculations, but essentially gravitational pull is directly proportional to mass, and is a linear relationship ?.

This is just a general question on Gravity and Mass.
If you created a perfect sphere of a known element in the vacuum of space, which was 1 metre in diameter, i assume that it would exhibit a gravitational pull on other objects - although probably very weak.
If you then created another...
