Homework Help: Electric Field and Charge Density Problem.

  1. Apr 3, 2013 #1
    1. The problem statement, all variables and given/known data

    A line of charge starts at x = +x0 and extends to positive infinity. Consider two situations: tal electric flux through the paraboloidal L
    (a) a uniform linear charge density λ = λ0, uniform electric field of magnitude E 0 in
    (b) a coordinate-dependent linear FcihgaurgeePd2e4n.1s7ityPrλob(xle)m=s 1λ7 axnd/1x8.. wn in Figure P24.13. 0 0
    Determine the electric field at the origin for the both charge densitie

    2. Relevant equations

    3. The attempt at a solution
    Im afraid I genuinely dont know how to start this I just need some help on how to start it.

    Hi TheParksie101! Welcome to PF! :smile:

    Sorry, but your typing is a bit garbled. :redface:

    Generally, with these problems you find the field from a tiny section from x to x + dx, and then integrate over all values of x. :wink:
