Conducting spherical shell with point charge

  1. Oct 2, 2010 #1
    Hi, I received this question on my exam today and it stumped me...

    Conducting spherical shell of inner radius 0.045m and outer radius 0.18m, which has a net charge of zero.

    A charge Q of 5.5x10-5 is placed at the center, find the electric fields at point A (0.03m), point B (0.06m), and point C (0.2m).

    Also find the charge qin of the inner radius and qout of the outer radius.

    Relevant Equations
    E= qenc/(4pi*r2*epsilon_0)

    My Attempt
    Ea = 5.50x10-5/(4pi*(0.03m)2*epsilon_0)
