Thickness of thin film liquid was measured by capacitive measurement using rectangular electrode strips protruding from insulating surface. The electrodes are 60 mm long and 0.1 mm wide with 0.6 mm long space in between. The liquid has dielectric constant of 10 and is spread evenly between the electrodes. The total capacitance was measured to be 128 fF. Calculate the thickness of the liquid 0.1 mm 0.6 mm air 60 mm liquid
