    I am not really sure how to approach this problem. I have no idea how to do it. I can't understand how to read this graph.

    E = (Kq)/r^2

    Yes, this graph is very peculiar at first, and it took me a few minutes to realize what was going on. [Hint: Think about Gauss's law.]

    I am thinking about Gauss's law, but I still can't figure it out.

    The field inside the shell is due to the point charge at the center of the shell only while out side the shell is due to the charges at the center and on the shell..
