I got
660/9.8 * 486/9.8 * 6.673E-11/.47^2 = 1.00891E-6
John weighs 660 N, and Marcia weighs 486 N. Estimate the gravitational force between them when they are 0.47 m apart.
I've tried finding the mass of john and marcia by doing m=F*a (F being their weight in Newtons and a being 9.8 m/s^2). When I found their masses, I applied them to the equation F=(Gmm')/r^2. However the answer I got was 4.74e^(-7) and it was incorrect.
