Charge put on sphere

  1. Feb 6, 2009 #1
    1. The problem statement, all variables and given/known data
    the question is A conducting sphere has a diameter of 10 centimeters. If you measure its voltage to be 3700 V, what is the charge in μC you have put on the sphere?


    2. Relevant equations

    V=3700, D=0.1 m, V=kq/R

    3. The attempt at a solution

    3700= (8.987 * 10^9 * q)/.1

    q=.041 microcoloumbs.

    but it says im wrong?? am i making a mistake someplace?

    Careless ... maybe, but I suspect you will get over that.

    Stupid? Not likely. You were smart enough to ask here.
