1. The charge on a proton is +1.6x10-19c and that on an electron is -1.6x10-1°c. Does it mean that the electron
has a charge 3.2x10-19 less than the charge of a proton?
Answers
The sign has nothing to do with the charge itself. It is just a convention. Just because we write an electron's charge as −1.6×10−19, it does not make the electron negative or its charge to be less than that of a proton.
We could have called charge on a proton to be −1.6×10−19C and the charge on an electron to be 1.6×10−19C. It does not make any difference in physics. Everything will continue to work the way it should.
Saying that a proton has 3.2×10−19C of charge is not wrong. However, it is more useful to refer to the magnitudes while comparing charges. I would personally prefer to say negative 5μC is greater than positive 3μC as it conveys something useful.
However, when you are using those values in mathematical equations, you need to take their sign into account. In this case, (p+−e−) does give you 3.2×10−19C.
