1. ### Cylindrical Conductors Carrying a Current I -- Formula (?)

How can I' be the formula above? Is there any formula to get this same
2. ### Can we take the partial derivatives of φ and ψ here?

I was studying on partial derivatives, chain rule etc uptill now. Deadline of the homework is tomorrow night. I guess I will not be able to complete the homework. If someone would give me the solution I really appreciate it. Else I will quit the question. I know that here is not a question...
3. ### How the power of the voltage supply can be calculated?

This is a piece of a spectrometer question and this region above is the velocity selector region. The question says "What should be the power of the voltage supply that we will use in velocity selector region?". I think it is not a problem to just take this area about the question. I assumed...
4. ### How the power of the voltage supply can be calculated?

I didn't ask the question for anything about the kinetic energy of the particle. You misunderstood me . I just wondered that what is the voltage supply's power.
5. ### How the power of the voltage supply can be calculated?

It's that easy really? I supposed that I would do some complex calculations :/
6. ### How the power of the voltage supply can be calculated?

I spesified it on the homework statement.
7. ### How the power of the voltage supply can be calculated?

I know only these relevant equations for power. But here there is a different situation, we have a parallel plates which we don't have to know I current. How should I think of about this? I wonder if it can be thought of a capasitor or something? Assume that also we know E, B and velocity .
8. ### Mass spectrometer with a Lead element

And also, how can I calculate power of this voltage supply? This can be thought of a capacitor?
9. ### Mass spectrometer with a Lead element

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?
10. ### Mass spectrometer with a Lead element

Thanks for everything ! All the best
11. ### Mass spectrometer with a Lead element

Would you like to add something else? Because I am starting over to do the homework.
12. ### Can we take the partial derivatives of φ and ψ here?

I'll be hanged if I understand! Pardon but I'm just not be able to do these calculations. I'll glance at chain rule of partial derivatives. I guess we couldn't make progress.
13. ### How to solve the integral which has limits from (1,2) to (2,4)

I did what you said at #9. Can you check out that for me?
14. ### Mass spectrometer with a Lead element

I was talking about the same thing at #31. And because of we can't use these as m2-m1 in ## (r_2 - r_1) = r_2 (1 - \sqrt{\frac{m_1}{m_2}})## I calculated these m2 and m1 one by one. So in this way, we don't have to use actual mneutron I think. What do you think?
15. ### How to solve the integral which has limits from (1,2) to (2,4)

I found the potential function u like this: I don't know why but it seems correct to me.
