What is the capacitance per unit length

Reference no: EM13681296

A cylindrical capacitor has an outer conductor with a radius of 3.5 mm and an inner conductor with a radius of 2.1 mm. The two conductors are separated by vacuum and the entire capacitor has a length of 2.2m.

Part A

What is the capacitance per unit length?
