A charge +q is located at 3.000 cm, a second charge −2q is located at 8.000 cm, and a third charge +q is located at 11.00 cm. The magnitude of q is 1.250 μC. Assume that the positive direction is to the right, and use k = 8.988×109 N⋅m2 /C2 for the Coulomb constant. What is the force Fx on the charge located at x = 8.000 cm? Fx =
