AI Thread Summary
A user seeks assistance with a physics problem involving a charged cylinder and two external charges, specifically how to calculate the equilibrium distance of the charges from the cylinder using the method of images. The cylinder has a charge of +1, while the external charges are both -1/2 and positioned equidistantly from the cylinder's center. The user has made modifications to the original problem and provided additional details in a document. The discussion focuses on applying the method of images to solve the problem. Clarification and guidance on the calculations are requested.

Hi,
This is my first post, am excited to be here. Cutting to the chase here, i have a question that has been bothering me for a while.
The problem is there is a charged cylinder with charge say +1, and i have to charges outside say at a distance 'd' from the center of the cylinder such that they lie in a single staright line passing thorugh the center. Now i wish to find the equillibrum distance of the charges from the cylinder(by symmetry both are equsidistant from the center of the cylinder). Also the charges are -1/2. How can i calculate the distance using method of images.


thanks

some modification

The previous problem that i gave has some modification. I have written some details in the document.
Thanks

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.
