Hi, I have a question I really need the answer to this immediately please please help me I am really stressed out:

Question = A nucleus contains Z protons which on average are uniformly distributed throughout a tiny sphere of radius R. Find the potential (relative to infinity) at the center of the nucleus. Assume that there are no electrons or other charged particle in the vicinity of this bare nucleus.

Please if someone answers and explains it to me I will worship them. Please help!

What can I do I am new to this topic and don't know much about it.

Then maybe read the lecture notes and the book once or twice again. Then you do an attempt to solution, and write down all relations that you know of.

You just have to find the electric potential at the centre of a uniformed charged sphere of radius R with charge z times the proton charge.
 

Thread 'Direction of the magnetic field of an oscillating charge'

Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
