A long solid nonconducting cylinder has radius r = 0.65 meters. It has a uniform charge density of 3.7 C/m3. Consider a cylinderical container concentric with the charged cylinder, with radius R = 1.5 m, and length L = 2 m.
Calculate the flux through the barrel of the cylindrical container.
The Attempt at a Solution
I thought this problem would be pretty simple. Since the charged cylinder is enclosed by the cylindercal container, I used Gauss's law to calculate the net electric flux. I used the equation
Electric Flux = Charge Enclosed / 8.85 * 10 ^ -12
The first step I took was to calculate the charge enclosed. To do this I just multiplied the charge density by the volume. 3.7 * .65^2*pi*2 = 9.8.
Then, I just divided that number by the constant Eo, 9.8/(8.*5 * 10^-12).
However this did not give me the right answer. Help! What am I doing wrong?
