Using a torsion balance similar to the one used in the Cavendish Experiment, a group of scientists determined that the force of gravity between the small masses (q) and the large masses (Q) was 1.80 X 10 - 3 N when their separation distance (d) was 0.10 m. Suppose the separation distance (d) was then tripled to 0.30 m, what is the new force of gravity between q and Q? Explain your answer using words or proportionality equations.
