Homework Help: Electric Field-Dimension Analysis

  1. Mar 1, 2017 #1
    1. The problem statement, all variables and given/known data
    Theres a rod and charge density ##λ## is a function of ##x##, so simply ##λ(x)=bx## and b is a constant.Find the dimension of ##b##
    and Find the total charge If the lenght of rod is L

    2. Relevant equations
    Dimension Analysis equataion


    3. The attempt at a solution
    I am thinking like rod is 1 dimensional object so the dimension of b will be ##\frac {C} {m^2}## and total charge of rod will be,
    ## Q=\int_0^L λ(x) \, dx## and from that ##Q=\frac {bL^2} {2}##

    Is this true ?
