1. The problem statement, all variables and given/known data two charges with the same charge q and mass m are moving with the same acceleration at each instant. calculate the separation between them. 2. Relevant equations 3. The attempt at a solution F=kqq/r^2 so, F= k q^2/r^2 r^2=kq^2/F let the acceleration be a, then F=ma. r= q√k/F =q/√4πε0ma but the answer given is q/√4πε0m where did I go wrong ? can someone explain please?
