Will a charged air variable capacitor try to turn itself towards the maximum setting? :-) Yes, of cose! Remember electrostatic voltmeter. It is a variable capasitor with pointer and elastic someone (
My guess is the 10uF capacitor becomes 1uF and the voltage rises to 100V. That's my guess too, but... W [stored energy] = V^2*C / 2: With oil: V=10V, C=10u => W = 10*10*10u / 2 = 500 uJ Without oil:
It's easier to imagine work done in hauling out a thin piece of plastic from between two charged plates rather than sucking out some liquid - does the liquid oil stick between the plates like a stron
