## Homework Statement

Charged-line 1 (parallel to x-axis, lying on y=0m) has a charge per unit length of 4.66 microC/m.

Charged-line 2 (parallel to line 1, lying on y=.414m) has a charge per unit length of -2.5 microC/m.

Question: What is the magnitude of the net electric field at a point .202m on y-axis?

## Homework Equations

I've got the formula E=sigma/epsilon-zero, but have not used it in an application yet. Very confused as to what to do.

Does the point being at .202m on y-axis have any relevance other than that it is INBETWEEN the two charged lines? Is the ".202m" arbitrary?

## The Attempt at a Solution

I did (4.66 x 10^-6)/epsilon zero + (-2.5 x 10^-6)/epsilon zero and got a wrong answer. This stuff is very confusing to me and any help would be amazing.
