A Parallel plate capacitor is charged fully using a 48 V battery such that the charge on it is 230 pC and the plate separation is 3 mm. The capacitor is then disconnected from the battery and the plate separation doubled. What is:

The new charge on the plates after the separation is increased

   


The new potential difference between the plates

   

The Field between the plates after increasing the separation

   

How much work does one have to do to pull the plates apart.

An isolated parallel-plate capacitor (not connected to a battery) has a charge of Q = 4.8×10−5C. The separation between the plates initially is d = 1.2 mm, and for this separation the capacitance is 3.1×10−11F. Calculate the work that must be done to pull the plates apart until their separation becomes 9.1 mm, if the charge on the plates remains constant. The capacitor plates are in a vacuum.
