Electric feild and a conducter

  1. Feb 3, 2010 #1
    1. The problem statement, all variables and given/known data

    The problem shows a picture of a spherical conductor that is placed some distance away from a positive charge.

    It wants me to draw in how I think the charge will be distributed.

    2. Relevant equations

    E=(KQq)/r^(2)

    3. The attempt at a solution

    My original thoughts were that the negative charge would be on the side closest to the positive charge because opposite charges attact.

    But then

    I remembered that the E feild inside of a conductor is always zero. So then I figured that the positive charges would be on the side closest to the positive charge because the e feild of the charges on the right side of the sphere need to be facing the opposite direction as the e feild from the outside charge in order for the e feilds to cancel each other out inside the sphere.

    Is this right?

    It just throws me off a little bit because I know that opposite charges attract.

    I noticed my post didn't make much sense there towards the end but I just edited so hopefully it makes sense now if anyone was having trouble understanding what I was saying.
