Homework Help: Electric Field

  1. Jan 18, 2009 #1
    1. The problem statement, all variables and given/known data
    Show the electric field inside an empty cavity in a conductor is zero, even if there is a charge outside the conductor. If a charge is placed inside the cavity, will there be an electric field outside the conductor. Explain Clearly. Assume that both the conductor and cavity are arbitrary of both shape and size

    2. Relevant equations

    3. The attempt at a solution

    As per PF rules, you are required to show some attempt at the problem before we help you.

    Hint: Think Gauss' Law:wink:
