Homework Statement
Hello, the problem i have with finding the potential is the integration limits. Assuming both the rod and point lies on the x axis. When i integrate the sum of many slices of rod, ill get 2 answers(negative and positive) depending on the limits i use.
Example i ended up integrating dx/x which means that if i set the far end of the rod as lower limit ill end up with ln(x/L+x) instead of ln((L+x)/X).
So the question is which of it is true and is there a standard way to approach this?
