Two identical boxes are placed on a floor. The coefficient of static friction between the boxes and the floor is 0.35. A force P1 is applied to the left box and causes it to move at a constant velocity. A force P2 is applied to the right box and causes it to move at a constant velocity. What can be inferred about the relative magnitudes of the forces P1 and P2? A. P1 > P2 B. P1 = P2 C. P1 < P2 D. There is not enough information to infer anything about the relative magnitudes.
