V PartA A cylindrical capacitor consists of a solid inner conducting core with radius 0.300 cm , surrounded by an outer hollow conducting tube. The two conductors are separated by air, and the length of the cylinder is 13.5 cm . The capacitance is 39.0 pF . Calculate the outer radius of the hollow tube. m muest Answer V PartB When the capacitor is charged to 150 V , what is the charge per unit length A on the capacitor? m muest
