A parallel-plate capacitor with plate area 3.3cm2 and air-gap separation 0.45mm is connected to a 12 V battery, and fully charged. The battery is then disconnected.
What is the charge on the capacitor? Q1=78pC
The plates are now pulled to a separation of 0.55 mm. What is the charge on the capacitor now? Q2=78pC
What is the potential difference across the plates now? V2=15V
How much work was required to pull the plates to their new separation? Express your answer using two significant figures. W=_________J
I got 1.1682*10-10J and it was wrong. Thanks for the help!
