However, the work done should be positive because the charge is positive and thus it accelerates in the same direction of the electric field. This means the angle between them = 0 and because it's a dot product it's cosine the angle between the electric field and the charge movement which is +1. If the charge is negative then it would accelerate in the opposite direction making a 180 degrees, and cosine will be -1 and so will the work become also negative Right?
