1. ### B Finite difference problem

I found this part of forum the most relevant to this theme so excuse me if I missed. This year I'm doing a high school summer project related to quantum mechanics. Anyway I'm using finite difference method to solve Schrodinger equation. Before starting to work on a project I decided to get some...
2. ### Eletrostatic problem

I think you are absolutely right . I got confused about the marks how dumb. THANKS ! I got this for the final solution: $$Q(t)=Q_0\cdot e^{-t\frac{s}{e_0}}$$ I don't think so because it's problem for high school students and they usually don't study Maxwell's equations. I've just finished...
3. ### Newbie Questions about Units in Physics Equations

You know that is work A[J]=F[N]*s[m] => J=kg* (m/s)^2 From here you can see that if the c is in m/s them mass must be in kg.
4. ### Eletrostatic problem

[Note from mentor -- this post was moved here from another forum] Hi, I ran to this problem today and i try to solve it but i can't complete it so if anyone can help me :) Sphere has a charge Q0. Inside the sphere is vacuum and outside the air. Consume that air has small non zero conductivity...
5. ### Total work

Ok, if it says that change of internal energy is part(for example 1/3) of TOTAL work executed over system(body). Does it mean that is TOTAL work indeed sums of every single work(mechanical work+internal energy change+...) ?
