1. Athin rod of length W has uniform charge per length 2. Find the electric potential (voltage) at the position
P as shown. Assume V = 0 at r = ∞ for problems on this worksheet.
Use the integration variable u as defined in the diagram to
write the voltage at point P. Include the limits of
integration but you do not need to evaluate the integral.
Hint: break up the rod into small pieces of length du and
use the point charge formula for the voltage due to the
small piece dV = Kdq/r with dą and r written in terms of
the givens A, L, z and integration variable u and du.
