Answer to Question #261482 in Electricity and Magnetism for 1234

Question

what is total charge on an infinite wire carrying a charge density $\lambda$=1/$\mid$ x$\mid$ +$\alpha$ where $\alpha$ is a constant find electric potential at a point whose perpendicular distance from the wire at x=0 is R

Answer 1

The electric potential is

$$E=\frac{2\lambda}{4\pi\epsilon_0}.$$
