    Hall effect over a conducting ring

    @kuruman No need to get so defensive man, your answer was perfectly to my liking. I simply didn't understand exactly what you were saying. But I see now why you want to take the line integral around the semi-circle; that should probably be it. Thank you. And yeah the link you mentioned is what...

    Hall effect over a conducting ring

    @kuruman Sorry, but I don't understand how that will help me. Wouldn't that just give me ##-\Delta V## between ##a## and ##b##? I already have that, don't I?

    Hall effect over a conducting ring

    This is the diagram provided in the question: The ring is made of conducting material. I was originally asked to find the potential difference between ##a## and ##b##. I did so using the Hall effect (and assuming it would work as per normal in this situation). This got me ##\Delta V = vBl##...

    Electric Potential of a Sphere: A Puzzling Problem

    @Orodruin The choice of zero level is specified, it's the plane of charge. My bad for not including that. However, this method would still require the method of image charges, which we are not taught in this course. But thank you for your time regardless.

    Electric Potential of a Sphere: A Puzzling Problem

    @BvU Thank you for your answer. I've looked around prior to this and come across the method of mirror charges, but the course I'm currently taking doesn't teach that, so there should be some other way to do the question. As for its difficulty, the question is actually one part of one of the...

    Electric Potential of a Sphere: A Puzzling Problem

    I can calculate the electric field strength at any point above the plane with Gauss' Law (##E = \frac{\eta}{\varepsilon_0}##) and so the electric potential at any point a perpendicular distance ##z## above the conducting plane (##V=−\frac{\eta}{\varepsilon_0}z##). But I'm having trouble taking...
