  1. Hi I think there’s is something wrong with one of the steps in part i. As 4*10^4.5 is not equal to what you wrote as the final answer..

    perhaps im reading it wrong

    1. Well spotted. That’s a misprint in the question that I didn’t notice. As you point out, you can’t have a potential difference measured in keV because that is a unit of energy, not voltage. It means 5kV I’m sure.
