A parallel plate capacitor of two plates, each with area 90π cm2, is separated by 5 mm air-gap. Hie capacitor is initially connected to 100 V source. When an unknown liquid is filled between the plates so as to fill the air-gap. an additional charge of 95 nC is found to be flowing onto the capacitor from the 100 V source. Hie dielectric constant of the liquid is
