There is a single charge in space with nothing else nearby. Which of the following quantities are present: (select all that apply). 

A capacitor of capacitance C has two parallel plates a distance d apart. The area of each plate is A. It is fully charged with a magnitude of Q charges on each plate. If we now lower Q, how does that change the capacitance value? Assume no other changes are made.
