(I've already solved this problem -- but the next question is a continuation)

So the FIRST QUESTION (which I've solved):

If a Van de Graaff generator is charged to 50,000 volts, how much energy does it take to add an additional electron to the charge on the sphere?

*my answer: 8.0 x 10^-15 joules*

NOW THE SECOND QUESTION is the one I don't understand.

How would the voltage of the generator in Part (A) compare to the voltage of a larger Van de Graaff generator with the same amount of charge? To which generator could an electron be added with the least expenditure of energy?

......"How would the voltage.. [50,000V] ..compare to the generator of a larger VdG generator WITH THE SAME AMOUNT OF CHARGE?"

---what does that mean?---

I know that the larger generator can be charged to a higher voltage...

is that the answer??

Thanks in advance!!!
