1. The problem statement, all variables and given/known data One electron has a mass of 9.11x10^-31 KG. Find the force 1.0 gram of electrons would exert on another 1.0g of electrons from 1.0 kilometer away F = ? Melectron = 9.11x10^-31 kg --> (0.01kg of electron = 9.11x10^-33 kg) Electron Coloumb = 1.6x10^-19 C (ignoring the negative sign b/c it is a vector) R = 1000m 2. Relevant equations F=(kQ1Q2/R^2) Since they are the same mass F = kQ^2/R^2 3. The attempt at a solution K = 9x10^9 R = 1000^2 What is the value for Q? I am not sure because any value I try to enter is invalid. Answer is 2.8x10^20N and I am getting a negative power answer when I try. Can someone steer me in the right direction please?
