    Please help a girl who doesnt understand physics!!!

    Plz help me with this problem!! I'm totally lost.
    1) Sketch the electric field lines both between and outside two concentric conducting spherical shells when a positive charge q1 is on the inner shell and negative charge -q2 is on the other one. Explain your diagrams using the concepts of flux and Gauss's law. Show the difference between the cases q1>q2, q1=q2 and q1<q2.

    I'm not sure quite how 2 sketch field lines. Please help me!! Thanx!!!

    In this case, the field lines are just radial lines between the two shells.
