Two test charges are located in the xy plane. Charge q1 = −4.250 nC and is located at x1 = 0.00 m, y1 = 0.6800 m. Charge q2 = 3.200 nC and is located at x2 = 1.500 m, y2 = 0.400 m. Calculate the x and y components, Ex and Ey, respectively, of the electric field E→ at the origin, (0, 0). The Coulomb force constant is 1/(4πϵ0) = 8.99×109 N⋅m2 /C2. Ex = N/C Ey = N/C
