Two large parallel plates have been oppositely charged. There is a uniform electric field E~ present between the plates, as shown in the fig- ure. A proton, with mass mp, is released from the positive plate at the same moment as an elec- tron, with mass me, is released from the negative plate. Ignore the force that the two charges exert on each other. What fraction of the way to the negative plate has the proton moved by the time the electron passes it?

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
