  1. Identical point charges of +1.1 ¦ÌC are fixed to three of the four corners of a square. What is the magnitude q of the negative point charge that must be fixed to the fourth corner, so that the charge at the diagonally opposite corner experiences a net force of zero?

  2. F = m a

    F = E q same for both where q = electron charge, + for proton, - for electron

    m = mass electron for electron
    m = mass proton for proton
