Question

We had a finite line of charge, of length L and total charge Q, centered at the origin.

1.Using result for the electric field a distance x away from the center of the rod: E=K?(1/(x-(L/2))-1/(x+(L/2))) and the definition of electric potential difference to find a formula for the electric potential a distance r from the center of the charged rod along its axis, find the absolute potential by taking the initial point where we have defined V = 0. (Hint: after performing the integral, but before evaluating it, use log properties to avoid problems with the log of infinity.)

2.Use the formula for the electric potential for a point charge to find the electric potential a distance r from the center of the charged rod along its axis. Does this match your formula from part a? (hopefully it does
