How would I solve this? I attached the screenshot.  

Consider a parallel-plate capacitor with plates of area "A" with one plate connected to a spring having a force constant
"k", and another plate held fixed. The system rests on a tabletop as shown in the figure below.

а Ь
If the charges placed on plates a and b are given by values Q+ and Q-, respectively, once the system is in equilibrium how
far does the end of the spring move from its original relaxed position? Hints: at equilibrium, what can we say about the
net force on plate a? How do we find the electrostatic force that acts on the plate using the electric field between the
plates?
