1. The problem statement, all variables and given/known data Consider a straight line segment of 3L and with a linear charge density λ. Determine the electric field, E, of at point P, which is a point within the segment and along the axis. (figure attached) 2. Relevant equations dE=kdQ/r^2 3. The attempt at a solution I attempted solving it but I am stuck at the integration part because i don't know from and up to where to integrate it.
