Homework Help: Point Charge and Charged Sphere

  1. Feb 3, 2015 #1
    1. The problem statement, all variables and given/known data
    A point charge q1 = -6.1 μC is located at the center of a thick conducting shell of inner radius a = 2.8 cm and outer radius b = 4.8 cm, The conducting shell has a net charge of q2 = 2.6 μC.

    2. Relevant equations
    E = (kQ)/r2
    F = (kq1q2)/r2

    3. The attempt at a solution
    I honestly do not know how to approach this problem mostly because I've been dealing with point charges. I'm not sure how to find the field of a charged sphere. I'm sure once I get this part down, the rest will follow. Thanks to any and all that can help, I really appreciate it; This is probably the most difficult time I've had with physics (to date).

    What is the question?

    Do you know Gauß' law?
