T B A FO P Two identical blocks A and B are connected by a lightweight rope. Block A is pulled to the right by a constant force Fo. The blocks are moving to the right across a rough surface and approach point P, where the rough surface transitions to a surface with negligible friction. How does the tension, T, in the rope connecting the blocks change, if at all, as block A passes point P? (A) T decreases. (B) T increases. (C) T remains constant. The change in T cannot be determined without knowing the coefficient of friction and the mass of the blocks
