Question: From Gausss law, the electric field set up by a uniform line of charge is E = (A/ Єr) r Where is a unit vector

From Gauss’s law, the electric field set up by a uniform line of charge is E = (A/ πЄθr) r
Where is a unit vector pointing radially away from the line and 1 is the linear charge density along the line, derive an expression for the potential difference between r = r1 and r = r2.
