Question
Transcribed Image Text:A parallel plate capacitor, in which the space between the plates is filled with a dielectric material with dielectric constant K = 3, has a capacitance of C=870 µF and it
is connected to a battery whose voltage is V=39 V and fully charged. Once it is fully charged, it is disconnected from the battery and without affecting the charge on
the plates, dielectric material is removed from the capacitor.
How much change occurs in the energy of the capacitor; final energy minus initial energy? Express your answer in units of mJ (milli Joules) using zero decimal places.
