A parallel plate capacitor A is filled with a dielectric whose dielectric constant varies with applied voltage as K=V. Initially A is uncharged. An identical capacitor B of capacitance ${\mathrm{C}}_0$  with air as dielectric is connected to voltage source ${\mathrm{V}}_0=30\mathrm{V}$ and then connected to the first capacitor after disconnecting the voltage source. The charge and voltage on capacitor
