  1. 1. Disagree on local scale. Gravity is weaker than electrostatic, unless your masses are huge. It is sort of an unanswerable question though.
    2. Disagree. G M1M2/ r^2 / k Q1Q2/r^2
    3. yes, 1/r^2 / 1/r^2 = 1
    4. well, remember problem 1 ? [7*10^-11*(81^10^-62)] /[9*10^9*(2.6*10^-38)]
    is about 2.4*10^-43
    5. now you do one
