A particle of charge q> 0 flows in a uniform electric field E with no external force for a total distance d starting from rest. A) Suppose the field is varying according to E = (2/11) Axi, where y is the vertical coordinate. The charge q travels from point y1 to point y2, where the total traveled distance is d. Taking y1 = = 0, enter an expression for the potential difference that the charge traverses in terms of the available symbols. B) If the charge q = 7.16 C, distance d = 21 m and the constant is A = 24.1 V/m2, how much work, in joules, is done on the charge while it traverses the potential difference in part (b)?
