Three point charges are shown below. q = 2.0 C, q2 = 4.0 C, and q3 = -2.0 C. d = 20 cm and d2 = 10 cm. What is the magnitude of the net electric force on 92, in Newtons? Use K = 9.0 109 Nm/c. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 91 92 93 + d + d2
