A teacher wants you to create a door lock that only opens when three charges placed in a straight, horizontal line are all in equilibrium. The outer two are equal to 10 mC and are separated by 3.0 cm. What is the charge on the middle one (directly between the other two)? Please show all work with equations that are used.
