Electric Energy stored in the sphere E=(12)CV2  where C=4πϵ0r  for this problem for the first sphere E1=12C1V12  C1=4πϵ0r1  E1=124πϵ0(0.131m)(89.6V)2  =(0.5)(4⋅3.14⋅8.85⋅10−12)(0.131m)(89.6V)2  for this problem forthe second sphere E2=12C2V22  C2=4πϵ0r2  E2=12(4πϵ0)(0.155m)(89.6V)2  =(0.5)(4⋅3.14⋅8.85⋅10−12)(0.155m)(78.3V)2  the electric energy contained in this space E=E1-E2
