Four charges are evenly spaced along the x-axis as shown, with a separation d = 3.0 cm. d_d_d 91 92 93 94 The values of the charges are: 91 = +4.0 ?C 92 = -2.0 ?C 93 = +2.0 ?C 94 = +6.0 ?C What is the magnitude of the net electrostatic force acting on charge q? due to the other charges? Express your answer in N, to at least one digit after the decimal point.
