Starting from rest, and under the influence no external force, a particle with a positive charge q moves a total distance d in a uniform electric field, E. Suppose the field is varying according to E=(2/11)Ayĵ where y is the vertical coordinate. The charge q travels from point y1=0 to point y2, where the total traveled distance is d. Calculate an expression for the potential difference that the charge experiences only using the symbols θ, A, d, g, m, or y2.
