Cylindrical capacitors: A cylindrical capacitor is made of two thin-walled concentric cylinders. The inner cylinder has radius
= 4.0 mm, and the outer one a radius
= 8.0 mm. The common length of the cylinders is L = 150 m. What is the potential energy stored in this capacitor when a potential difference 4.0 V is applied between the inner and outer cylinder? (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2)
