A uniform electric field of magnitude 640 N/C exists between two parallel plates that are 4.40 cm apart. A proton is released from the positive plate at the same instant that an electron is released from the negative plate. (a) Determine the distance from the positive plate at which the two pass each other. (Ignore the electrical attraction between the proton and electron.) Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. µm (b) Repeat part (a) for a sodium ion (Na+) and a chlorine ion (Cl-). cm
The ground state for a single valence electron of a rubidium atom (Z=37) is 5s and its energy is –4.18 eV. The valence electron is excited into the 5g state. We want to determine the energy of this 5g electron. Assume that the wave function for th..
