Four 9.5 kg spheres are located at the corners of a square of side 0.70 m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three.
What is the magnitude? ___ N
Figure the vector of the opposite corner, and the adjacent corners will have vectors at 45 deg, so
Force = opposite force + 2*forcecorner*.707
remember the opposite distance is .7*1.4
