1 10. Given two particles with 2.00-μC charges as shown in Fig- ure P25.10 and a particle with charge q 1.28 X 10-18 C at the origin, (a) what is the net force exerted by the two 2.00-μC charges on the test charge q? (b) What is the electric field at the origin due to the two 2.00-μC parti- cles? (c) What is the electric potential at the origin due to the two 2.00-μC particles? y 2.00 μC 9 2.00 με x x = -0.800 m 0 x = 0.800 m Figure P25.10
