## A very long uniform line of charge has a charge per unit length of 4.82 uC/m

1. The problem statement, all variables and given/known data
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

2. Relevant equations

EA=PA/epsilon-nought
E=kq/r2

3. 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..?
