일반물리학 1 — Gravitation: Problem 26

26 In Fig. 13-28, three 8.00 kg spheres are located at distances \(d_1 = 0.300 \text{ m}\) and \(d_2 = 0.400 \text{ m}\). What are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the net gravitational force on sphere B due to spheres A and C?
