Question

Part A and B Please.

A capacitor is made from two hollow, coaxial, iron cylinders, one inside the other. The inner cylinder is negatively charged and the outer is positively charged; the magnitude of the charge on each is 12.0 pC. The inner cylinder has a radius of 0.300 mm, the outer one has a radius of 5.20
mm, and the length of each cylinder is 12.0 cm. 


Part A
What is the capacitance?
Use 8.854×10−12 F/m for the permittivity of free space.
