1. The problem statement, all variables and given/known data A positive charge Q is fixed to the origin. A negative charge with magnitude 9Q is fixed along the positive x-axis a distance d to the right of the origin. Determine a point where a small positive test charge q will experience zero electrical force from the two charges, or show that there is no such point. Draw diagrams to help you. 2. Relevant equations FE = kq1q2 / r2 3. The attempt at a solution (+Q)--------d---------(-9Q) I know the test charge must be to the left of the positive charge Q, and I tried to solve by rearranging the equation to solve to r, but that leaves you with dividing the force, which in this case is zero which does not work. r = √kq1q2 / FE But FE = 0 so this does not work.
