Worksheet: Charge Enclosed in a Cylindrically Symmetric Region
In this worksheet, we will practice using Gauss's law to find the electric field around a cylindrically symmetric distribution of charge.
The electric field at 2.0 cm from the center of long copper rod of radius 1.0 cm has a magnitude 3.0 N/C and is directed outward from the axis of the rod.
What is the charge per unit length of the copper rod?
- A C/m
- B C/m
- C C/m
- D C/m
- E C/m
What would be the electric flux through a cube of side 5.0 cm situated such that the rod passes through opposite sides of the cube perpendicularly?
- A 0.019 N⋅m2/C
- B 0.012 N⋅m2/C
- C 0.022 N⋅m2/C
- D 0.027 N⋅m2/C
- E 0.0090 N⋅m2/C
