    hi sharma! :smile:
    if you mean "where does the energy come from?", the answer is that it comes from whatever force is making the electron accelerate

    when you accelerate an electron, you not only have to give it extra momentum, you also have to supply a bit of work into the electromagnetic field :wink:
