Question
A 2.0-nF parallel plate capacitor with a sheet of mylar (k = 3.1) filling the space between the plates is charged to a potential difference of 90 V and is then disconnected. What is the potential difference between the plates of the capacitor once the mylar is completely removed?

What is the potential difference between the plates of the capacitor once the mylar is completely removed?Explanation / Answer
Q = 90*3.1*2*10^-9
potential difference = Q/2*10^-9 = 2800
therefor D
