Energy stored in electric field

  • #1
I know that energy stored in electric field / unit volume = 1/2 ε E2

so can I say that for any configuration calculating ∫ ½ ε E2 over whole space - gives me the potential energy stored stored in the system

for instance
for →
Q1 °




° Q2 ....separated by distance 'd'

∫ ½ ε E2 over whole space = KQ1Q2 / d

Please check your final equation. You integrated energy density over space and got a force!

If you still have questions, you should ask them, instead of barking orders at us.
