A uniform electric field of magnitude 640 N/C exists between two parallel plates that are 4.00 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.)
(b) What If? Repeat part (a) for a sodium ion (Na+) and a chloride ion (Cl-).
