I actually found out. I had to set V = (k*delta Q)/r and integrate it, setting r as sqrt(R^2 + h^2), setting range between 0 and h.
Acknowledging delta Q = Q/L where L is the length, integration will give same result as given.
A tricky part for me was where h came from on the constant side. I...
Hello dear physics masters on earth, I am very grateful to be priviliged to ask you a question regarding electric fields and potential of a single-cpin helix. It is portrayed as below.
It is a line of uniform charge, and 1-turn helix with radius R and height H. I have came to ugly answers, and...
