Aparallel-plate capacitor initially has air (k= 1) between the plates. we first fullycharge it by a 12 v battery. after the battery is disconnected, we insert a dielectricbetween the plates and it completely fills the space in between. a voltmeter is placedacross the capacitor and it reads 3.6 v now.(a) assuming that there is no charge loss during the process, what is the dielectricconstant of this material? (b) what’s the fraction of the stored energy changed by inserting the dielectric? (c) what will the voltmeter read if the dielectric is pulled partway out so that it fillsonly half of the space in between the plates?
