I Energy stored in electric field

  1. Apr 14, 2016 #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!

    Oh ! I meant interacting potential energy

    have corrected that !!

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