Homework Help: Electrostatics

Posted by Dan on Thursday, February 28, 2008 at 10:00pm.

A linear charge rho L = 2.0 uC lies on the y-z plane. Find the electric flux passing through the plane extending from 0 to 1.0m in the x direction and from -infinity to infinity in the y direction.

Alright, so the formula to use is:

flux = (integral(integral)(Ds * dS)) where dS is a vector whose direction is normal to the surface element ds and has a magnitude of ds and Ds is the electric flux density passing through ds.

Ds is usually = Q / (4pi*R^2)

I have no idea what to make dS or how to start this. Any hints/tips?
