1. The problem statement, all variables and given/known data a conducting sphere of radius R has charge +Q on its surface. if the charge on the sphere is doubled and radius is halved, the energy associated with the electric feild will be? 2. Relevant equations electric feild = K * Q/(R*R) Energy associated with feild will be (1/2)Integral of (ebsilon)E*E 3. The attempt at a solution what am getting as answer is 64.but that is wrong. how can i solve this?
