Three identical charges of q = 8 µC each are placed in a line with 5 cm between each charge (e.g. one at x=0, another at x=5cm and the last at x=10cm). If a charge on the end of the line is released, while the other two are held fixed, how fast will the released charge be going when it is very far away? Take the mass of the moving charge to be m = 85 g, and ignore all forces other than the Coulomb force. (a) 20.2 m/s (b) 30.5 m/s (c) 51.2 m/s (d) 87.4 m/s
