A particular charge distribution produces an electric field along the x-axis of the form, a/x2, where a is a positive constant. Find the expression for potential difference, on the x-axis, between x = A and x = B. That is, find V (B) – V (A). What charge distribution produced this?
An electric field of strength E = 4700 N/C is directed along the +x-axis as shown. 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...
