The point masses m and 2 m lie along the x -axis, with m at the origin and 2 m at x = L . A third point mass M is moved along the x -axis. (a) At what point is the net gravitational force on M due to the other two masses equal to zero? (b) Sketch the x -component of the net force on M due to m and 2 m , taking quantities to the right as positive. Include the regions x < 0, 0 < x < L , and . x > L . Be especially careful to show the behavior of the graph on either side of x = 0 and x = L .

a square of edge length 20.0 cm is formed by four spheres of masses m1 = 5.00 g, m2 = 3.00 g, m3 = 1.00 g, and m4 = 5.00 g. In unit-vector notation, what is the net gravitational force from them on a central sphere with mass m5 = 2.50 g?
A 20 kg sphere is at the origin and a 10 kg sphere is at (x, y) = (20 cm, 0 cm). At what point or points could you place a small mass such that the net gravitational force on it due to the spheres is zero?
Two identical uniform spheres A and B, with mass M=M= 1.00 [kg], are placed 0.500 [m] away from another spherical mass C with mass m=m= 0.300 [kg] as shown:
If mass C is released from rest, what is its net acceleration? Assume that only the gravitational forces from spheres A and B act on C. State also the direction if it is upward or downward.
