How does the direction of friction relate to the direction of motion

We know that the magnitudes of the negative charge on the electron and the positive charge on the proton are equal. Suppose, however, that these magnitudes differ from each other by 0.00040%. With what force would two copper coins, placed 1.

A block M = 1.25 kg is pulled up along an inclined plane by a constant force F which is parallel to the incline as shown. The coefficient of kinetic friction between the block and the plane surface µk=0.35. The block starts from rest at the bottom.
