359237 A parallel plate capacitor having a separation between the plates \(d\), plate area \(A\) and material with dielectric constant \(K\) has capacitance \({C_o}\). Now one-third of the material is replaced by another material with dielectric constant 2\(K\), so that effectively there are two capacitors one with area dielectric constant 2\(K\) and another with area \(\frac{2}{3}A\) and dielectric \(K\). If the capacitance of this new capacitor is \(C\) then \(\frac{C}{{{C_o}}}\) is
