How much of potential energy stored in conducting sphere

  1. Feb 15, 2009 #1
    Hi,
    can anyone help me to solve this problem.....

    An isolated conducting sphere which radius R is 6.85cm has a charge q=1.25nc. Determine how much potential energy stored in conducting sphere?

    I try to solve it but can't get the ans....the hint given is by using c=4(pi)ER
    answer is =103nJ

    thanks for helping
