Hi everyone :-) This is my first post here!
I have a question regarding electrostatics, in the picture above. I am not looking for the solution at all as this work will be assesed, I am just hoping that someone can verify/ poke me in the right direction.
First of all potential is q/(k*x) in x-hat direction?
Integrate that over 2*Pi*a to get potential of a hoop.
Using cosine rule to express x in terms of theta, then integrate over whole hoop from 0 to Pi..
Thats what I have been trying, and I am not having any joy. Any small pointers would be most appreciated!
I hope that was okay for a first post!
