11. Three charges are arranged in a straight line. The first charge has a charge of -6.0 µC, the middle charge has a charge of -8.0 μC and is 45 cm from the first charge, and the third charge has a charge of 14.0 µC and is 25 cm from the middle charge (opposite side from the first charge). First, draw a picture of the charges (similar to figure 16-19) with an x-axis. Calculate the net force acting on the first charge (-6 µC) due to the other two charges. Remember to give the direction relative to your x-axis. 2. For the same arrangement of charges as in problem 11, calculate the electric field strength at the position of the first charge due to the other two charges. In other words, if the -6.0 μC is removed then what is the electric field at that location due to the other two charges?
