A capacitance gauge consists of a 5mm diameter cylinder which is slid into a tube with an inner diameter of 6mm. Air (K = 1) separates the two surfaces. A capacitance value of 3.5pF is measured. How far into the tube has the cylinder slid? Express your answer in mm and round to two decimal places. 1.22
