1. The problem statement, all variables and given/known data Given two particles with Q = 2.30 µC charges as shown in the figure below and a particle with charge q = 1.38X10-18 C at the origin, answer the following. (Note: Assume a reference level of potential V = 0 at r = ∞.) (a) What is the net force exerted by the two 2.30 µC charges on the test charge q? (b) What is the electric field at the origin due to the two 2.30 µC particles? (c) What is the electrical potential at the origin due to the two 2.30 µC particles? 2. Relevant equations F = (keQQ) / r2 E = kQ / r2 3. The attempt at a solution F = (9X109)(2.3X10-6)(1.38X10-18) / 0.82 F = 4.4634X10-14 4.46X10-14 N? No way... it can't be that small... What am I doing wrong...?
