Given two particles with Q = 1.70−μC charges as shown in the figure below and a particle with charge q = 1.24×10−18 C at the origin. (Note: Assume a reference level of potential V = 0 at r = ∞.) (a) What is the net force exerted by the two 1.70−μC charges on the test charge q? (b) What is the electric field at the origin due to the two 1.70−μC particles? N/C (c) What is the electrical potential at the origin due to the two 1.70−μC particles? kV
