The question is:
Find the gravitational field strength at the point A in terms of G.
So I went about assuming we use g = GM/r^2, for both masses, and then subtract them as we're meant to find the overall using vectorial addition.
But, the answer in the back of the book is G/4. I can't seem to get this whatsover.
Could someone run through the calculations please?
Thanks a bunch!
