i don't understand the why the answer Solution: D vec(E)= vec(grad) V so the point of the greatest gradient has the largest magnitude of the electric field (i.e. at E) and the point with the least gradient (i.e at B - zero gradient) has the smallest magnitude of electric field. A 19. An electrostatic potential V in a region is only a function of x. V(r) is shown in the figure below. Of the labelled points, the magnitude of the electric field is respectively smallest and greatest at: V(x) A. B and D D. B and E Solution: D Ü B B. C and D E. D and B C C D E C. A and E Ē = -VV so the point of the greatest gradient has the largest magnitude of the electric field (i.e. at E) and the point with the least gradient (i.e at B- zero gradient) has the smallest magnitude of electric field.
