Homework Statement



When finding the gravitational potential of a thick walled hollow cylinder from the

point P, located along the X-axis,

can I find the Gravitational potential of a solid cylinder and then subtract the
gravitational potential of a smaller (inner empty) cylinder?



Homework Equations



The Attempt at a Solution



This is my attempt to answer a much complicated problem.
I just need to make sure that I can subtract the two gravitational potential
to find the gp of hollow thick cylinder.

Any hint or help would be really appreciated thanks!

Yes … that's exactly the way to do it. :smile:
 
is the gravitational potential measuring from a point on Z axis same as the gp measured on a point on X axis?
 
(what happened to "one simple yes/no question"? :biggrin: :wink:)

If the Y-axis is the axis of the cylinder, yes. :smile:
 

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...
