A parallel plate capacitor has capacitance C, when there is vacuum within the parallel plates. A sheet having thickness

(\frac{1}{3})^{rd}

of the separation between the plates and relative permittivity K is introduced between the plates. The new capacitance of the system is :

rac{3KC}{2K + 1}

rac{CK}{2 + K}

rac{3CK^2}{(2K + 1)^2}

rac{4KC}{3K - 1}
