For b): I meant the resultant force on the 8 kg mass at the origin. Sorry!
calculate the two forces, magnitude and angle, add them. Compare it to this:
fx=G7*8/9 (-x) + G9*8/1 x add them to get net force in x direction.
fy=G7*8/1(+y) + G9*8/4 (+y) add them to get net force in y direction
Now add these as vectors.
I'm sorry, but I'm not understanding your explanation. I figured out the two forces and found the resultant but my answer is wrong and I'm not sure how to use your method.
What does the G stand for? The gravitational constant??
