A uniform electric field with a magnitude of 1200 N/C points in the negative x d

Question

A uniform electric field with a magnitude of 1200 N/C points in the negative x direction, as shown in the figure. What is the difference in electric potential, What is the difference in electric potential, Delta V = V_B - V_A, between points C and A? What is the difference in electric potential, Delta V = V_c - V_a, between points A and B? From the information given in this problem, is it possible to determine the value of the electric potential at A? If so determine the value of the electric potential at A; If not explain why.

Explanation / Answer

a) delta V = VB -VC = - Edelta X = - 1200 * 0.04 = -48 V

b) A and B are at same potential because there is no delta x in the drection of electric field

VB -VA = 0 because VB=VA

VC - VA = VC-VB = 48 V

C)potential difference A and B is 0V

d) No, not possible. determining the potential difference is possible but not potential at any point because potential of none other points are given.
