A cylindrical capacitor consists of a solid inner conducting core with radius 0.200 centimeter, surrounded by an outer hollow conducting tube. The two conductors are separated by air, and the length of the cylinder is 11.0 centimeter. The capacitance is 36.5 pF.
A) Compute the outer radius of the hollow tube.
B) When the capacitor is charged to 140 V, obtain the charge per unit length Lambda on the capacitor?
