What you'll learn

  1. Two like charges: Where two pushes cancel
  2. Unlike charges: Unlike charges: look outside
  3. Earth and Moon: Gravity has null points too
  4. Stable or not?: Stable or unstable balance
  5. Balance all three: Three free charges in balance
  6. Dipped in oil: A medium weakens every force
