Homework Statement
A solid metal spheres of radius a surrounded by a concentric thin metal shell of radius 2a. Initially botb are having charge Q each. When the two are connected by a conducting wire , then the amount of heat produced in process will be :
Homework Equations
Heat = E2 - E1
Energy = kq²/ distance [/B]
The Attempt at a Solution
So i first tried to calculate the energy in initial condition.
I got E1 = kQ²/a + kQ²/2a
Then when the spheres are connected, then i think charge of inner sphere flows to outer sphere so E2 = k(2Q)²/ 2a
Then i put in the formula E2 -E1, but didn't get the answer
