Mass vs Charge

The number of students in my honors class who did not distinguish between charge and mass is very alarming. Mass of a proton = 1.67^-27 kg as does mass of a neutron. Charge of neutron is, you guessed it, zero. Charge of a proton is 1.6x10^-19 Coulombs. Its time to start understanding that these symbols, Q and M, are real physical quantities. By now you must know that electric fields act on electric charges through F = Q Efield and that

a=Fnet /mass not /charge. Do not make these errors again.
