Two identical metallic blocks resting on a frictionless horizontal surface are connected by a light metallic spring having the spring constant 160N/m and an un- stretched length of 0.32m as shown. A total charge of Q is slowly placed on the system, causing the spring to stretch to an equilibrium length of 0.43m as shown. Determine the value of Q, assuming that all the charge resides on the blocks and modelling the blocks as point charges. State your answer in mC to nearest 0.01 mC. Take electric constant ke to be 8.99x10° Nm2/C2
