Question
The charge on a proton is +1.6 × 10−19 C and that on an electron is −1.6 × 10−19 C. Does it mean that the electron has 3.2 × 10−19 C less charge than the proton?
Solution
An electron and a proton have equal and opposite charges of magnitude 1.6 × 10−19 C. But it doesn't mean that the electron has 3.2 × 10−19 C less charge than the proton.
