A piece of plastic has a net charge of +2.00 μC.How many more protons than electrons does this piece of plastic have? (e = 1.60 × 10^-19 C)

Question

Quizplus · Accepted Answer

The net charge of +2.00 μC (or 2.00 × 10^-6 C) divided by the charge of a single proton (or electron), which is 1.60 × 10^-19 C, gives the number of excess protons. This calculation results in 1.25 × 10^13, matching option A.
