## Homework Statement

A very long uniform line of charge has charge per unit length 4.82 uC/m and lies along the x-axis. A second long uniform line of charge has charge per unit length -2.46 uC/m and is parallel to the x-axis at y1= 0.418

1-)What is the magnitude of the net electric field at point y2= 0.202 m on the y-axis?

2-)What is the direction of the net electric field at point y2= 0.202 m on the y-axis?

-y-axis

+y-axis

3-)What is the magnitude of the net electric field at point y3= 0.608 m on the y-axis?

4-)What is the direction of the net electric field at point y3 = 0.608 m on the y-axis?

-y-axis

+y-axis

## Homework Equations

EA=PA/epsilon-nought

E=kq/r2

## The Attempt at a Solution

I don't really know where to start.

At first I tried to do E=(k*dq)/r^2 = k(4.82e-6)/(x^2+.202^2)

But then realized that I don't have a definite integral. Then I tried to use E=(kq1/r1)+(kq2/r2)... but the answer was incorrect. Anyone know how to start this problem..?
