1. The problem statement, all variables and given/known data Two charged particles are fixed on the x-axis 11 cm apart. The one on the left has a net charge of +25uc and the one on the right has a net charge of -11uc. What is the magnitude of the electric field 10 cm to the right of the negative charge? 2. Relevant equations E = (kq)/r^2 3. The attempt at a solution When I plug in 9.0 x 10^9 for k, 11.0 x 10^-6 C for q and 0.1 m for r, I get the wrong answer. Thanks for any help!
