A uniform electric field with a magnitude of 1150 N/C points in the negative x direction, as shown in Figure 2?
A uniform electric field with a magnitude of 1150 N/C points in the negative x direction, as illustrated in Figure 20-21, where L = 1.2 cm (http://www.webassign.net/walker/20-21alt.gif).
(a) What is the difference in electric potential, ΔV = VB - VA, between points A and B?
(b) What is the difference in electric potential, ΔV = VB - VC, between points B and C?
(c) What is the difference in electric potential, ΔV = VC - VA, between points C and A?
(d) Based on the information provided in this problem, is it possible to determine the value of the electric potential at point A? Please explain your reasoning.

The diagram is far from clear. However:
(a) Since A and B are perpendicular to parallel field lines, ΔVAB = 0
(b) I can't see L on the diagram.
But if B and C are 1.2 cm = 0.012m apart, then ΔVBC = 1150 N/C * 0.012m = 13.8 Volts
(c) Use the dimensions to work out the vector magnitude and direction etc.
(d) No. Because no reference potentials are stated.
the version in electric ability is with reference to the electrical powered field in accordance to delta V = - E dot L the place dot skill the dot product such that E dot L = E L cos (theta) the place E is the potential of the electrical powered field, L is the separation between the two factors, and theta is the attitude between the sphere and the separation in this diagram, cos(theta) = 4L = 0.032m, so delta V = -(-1400N/C) x 0.032m = 40 4.8V
