Finding charge on conducting sphere

  1. Feb 8, 2010 #1
    I need to find the charge and charge density on the surface of a conducting sphere of radius r=0.15m and of a potential of V=200V.

    I know the surface charge density, which is Q/A. The surface area is 0.28274, but I can't find the charge.
