Homework Help: Electric Field

  1. Sep 26, 2013 #1
    1. The problem statement, all variables and given/known data
    A charge is located a distance 'a' above a sheet of metal. The charge density induced on the sheet of metal is (-2aQ)/(4pi(ρ^2+a^2)^(3/2)).

    Since there are no dimensions indicated for this plate, would it be plausible to assume that we are integrating from zero to infinity with the variable being ρ?

    Depends on what you want to find.
    But sure - that formula looks like the one for an infinite flat sheet of perfect, grounded, conductor.
    You could verify it by just doing the math.
