Exercise 24.10 Part A A cylindrical capacitor consists of a solid inner conducting core with radius 0.250 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 36.0 pF Calculate the outer radius of the hollow tube cm Submit My Answers Give Up Incorrect; Try Again; 5 attempts remaining Part B When the capacitor is charged to 125 V , what is the charge per unit length on the capacitor? | = 3.33×10-8 C/m Submit My Answers Give Up Correct

Explanation / Answer

cpacitance of spherical cpacitor

C = 4xpix epsilon (R1 R2 / R2-R1)

substituting given values we get

1/R1 - 1/R2 = 4xpix epsilon / C

1/R1 - 1/R2 = 3.0787

R2 = 0.252 cm
