A total charge of Q is uniformly distributed along a line, which extends along the x- axis from x=0 to x=L. What is the electric field due to this line of charge at a point P, which is on the x axis at x=a. Your answer should be a symbolic expression that only depends on the variables k, Q, a, and L. What does your expression reduce to when a≫L (far-field limit)?
