    1. The problem statement, all variables and given/known data

    Consider a spherical shell with radius R and surface charge density σ = σ0 cosθ
    (a) What is the total charge carried by the shell?
    (b) Please evaluate the charge carried by the upper hemisphere, in terms of σ0.



    2. Relevant equations

    Q=∫σ0 cosθ da


    3. The attempt at a solution
    For a), is zero correct?
    For b), I don't know how to do the integation.
