1. The problem statement, all variables and given/known data A charge of 3.5*10^-6 is fixed on the x-axis at x= 0.55m, while a charge of -15*10^-6 is fixed at the origin. What is the net electric field on the x-axis at 0.8m? 2. Relevant equations Fe = qE 3. The attempt at a solution Used Fe = qE, but that's it.
