Suppose that the electric potential ? in a certain region is given by V=Ax2−Bx+C where A=2.15 V/m2, B=3.65 V/m, and C=7.55 V. Find the magnitude of the electric field E at the point ?=1.35 m. E=?

The electric field magnitude on the surface of an irregularly shaped conductor varies from 56.0 kN/C to 28.0 kN/C. Can you evaluate the electric potential on the conductor? If so, find its value. If not, explain why not.

What is the potential difference between xi = 10 cm and xf = 40 cm in the uniform electric field Ex = 2000 V/m?

The potential in a region of space due to a charge distribution is given by the expression V = ax?z + bxy - cz? where a = -4.00 V/m3, b = 7.00 V/m2, and c = 4.00 V/m2. what is the electric field vector at the point (0, -9.00, -8.00) m? Express your answer in vector form. E = 63i + 64k Note that the potential is a function of three variables. Review rules for partial differentiation. V/m
