Here's my problem:(adsbygoogle = window.adsbygoogle || []).push({});

A parallel-plate air capacitor has a capacitance of 730 picoFarads. The charge on each plate is 2.95 microCoulombs.

a) What is the potential difference between the plates? I used the equation V=Q/C to get 2.4746E-4 V, but this is incorrect.

b)If the charge is kept constant, what will be the potential difference between the plates if the separation is tripled?

I think it would be divided by three.

c) How much work is required to triple the separation?

U=1/2 Q V

I think if I could calculate the potential difference correctly, I could work the rest of the problem. Any hints/help would be welcome!!!
