Question

How many protons are required to generate a charge of +25.0 C?

Answer 1

`N=1.56*10^(20)` protons

Step-by-step explanation:

The total charge Q+=+25.0C is the sum of the charge of the N protons, with charge q :

`Q_(+)=N*q_(p)`

q_{p}=1.6*10^{-19}C charge of a proton

We solve to find N:

`N=Q_(+)/q_(p)=25/(1.6*10^(-19))=1.56*10^(20)`
