The three spheres in the figure, with masses mA = 89 g, mB = 12 g, and mC = 17 g, have their centers on a common line, with L = 22 cm and d = 3 cm. You move sphere B along the line until its center-to-center separation from C is d = 3 cm. How much work is done on sphere B(a) by you and (b) by the net gravitational force on B due to spheres A and C?
