Question 25

Summary: For two parallel metal plates that are separated by a fixed distance and have a given potential difference applied; (a) Calculate the magnitude of the electric field strength between the plates. (b) Calculate the magnitude of the electrostatic force acting on an electron between the plates, (c) If a beam of electrons is fired with a given velocity between the plates, calculate the magnitude and direction of the magnetic field that must be applied between the plates to cancel the force and stop the deflection of the electron beam.
