Two uniform spheres, each of mass 0.260 kg, are fixed at points A and B (?Fig. E13.5?). Find the magnitude and direction of the initial acceleration of a uniform sphere with mass 0.010 kg if released from rest at point P and acted on only by forces of gravitational attraction of the spheres at A and B .

Step 1: Mass of sphere P M = 0.P0 kg Mass of sphere A M = 0.26 kg A Mass of sphere A M = 0.26 kg B Distance between masses P and A(or B) r = 10 cm = 0.1 m Distance between masses A and B 2d = 8 cm or d = 4 cm = 0.04 m
