1. The problem statement, all variables and given/known data Nobel laureate Richard Feynman once said that if 2 persons stood at arm's length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a "weight" equal to that of the entire Earth. Carry out an order-of-magnitude calculation to substantiate this assertion. 2. Relevant equations F = k |q1||q2| / r2 3. The attempt at a solution I had no idea to do this so i used Coulombs law with q1 = q1 = -e I used -e because it said theres 1% more electrons so if there's 100 protons, there's 101 electroons and 100 of the electrons would cancel out the protons so the net charge is 1 electron (e). but then It didnt said anything about r so i just guessed and used r = 2 m and then again with r = 1.5m but i got an answer that was x 10^-28 and the answer is supposed to be ~1025 Am I even using the right equation??
