An electric field of strength E = 4700 N/C is directed along the +x-axis as shown. What is the magnitude of the potential difference between point B and point A if the distance between these two points is 10 cm? An electron is initially at rest at point B. How much kinetic energy (in electron-Volts, or eV) will the electron gain by moving to...

The electric field in the xy-plane due to an infinite line of charge along the z-axis is a gradient field with a potential function V(x,y) = c In To 2 + y2 where c> 0 is a constant and ro is a reference distance at which the potential is assumed to be 0.
