Question

Item 12 l Review The figure shows four charges at the corners of a square of side L. Assume qand Qare positive. (Figure 1) Part A What is the magnitude of the net force on q? Give your answer in terms of Q. q, and constant K Submit Request Answer Provide Feedback

Answer 1

F^1 = 4 k Q_q/(squareroot 2 L)^2 = 4 k Q_q/2 l^2 = 2 k Q_q/L^2 F = kqQ/L^2 F_net = F^1 - squareroot 2 F = 2 k Q q/L^2 - squareroot 2 k q Q/L^2 F_net = (2 - squareroot 2 k Q q/L^2)
