Electrons are continuously being knocked out of air molecules by cosmic ray particles from space. once the electrons are free, they experience an electric force, f, caused by an electric field, e, that’s in the atmosphere due to charged particles that are already on earth. if the electric field near earth is 150 n/c and directed downward, what is change in potential energy, δu, when the force causes the electron to move upward through a distance of d=520 m? through what potential difference does the electron move?
