Mass spectrometer with a Lead element

[phyzguy]

You're right. The original problem didn't ask you to use the neutron mass, it just said, "The mass difference between two isotopes is sometimes just a neutron mass. The spectrometer should separate them very well."

Would you like to add something else? Because I am starting over to do the homework.

I think you've got the idea. A couple of things to remember:
(1) Clearly state the assumptions you are making.
(2) Make sure to keep enough significant figures so the error in your final answer is less than 10%, especially when subtracting two similar sized numbers like r2-r1.
(3) Always include the units!

Thanks for everything ! All the best

In velocity selector region, the question says "determine" but I did it like this below. I chose the voltage necessarily. Is there another way to determine these values?

And also, how can I calculate power of this voltage supply? This can be thought of a capacitor?
