Two point charges are located as shown in Figure P18.7, with charge q 1 = +2.5 C

Question:

Two point charges are located as shown in Figure P18.7, with charge q₁ = +2.5 C at x = -3.0 m, y = 0, and charge q₂ = +4.0 C at x = +1.0 m, y = +2.0 m. An electron is now taken from a point very far away and placed at the origin. How much work must be done on the electron to move it to the origin?
