A parallel plate condenser with oil (dielectric constant 2) between the plates has capacitance C. If oil is removed, the capacitance of capacitor becomes

A parallel plate condenser with oil (dielectric constant 2) between the plates has capacitance C. If oil is removed, the capacitance of capacitor becomes

A parallel plate capacitor with oil as a dielectric between the plates has a capacitance C. if the oil, with dielectric constannt (K=3), is removed, then the capacitance of the capacitor will be
