In this lesson, we will learn how to use 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?
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?
