(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 10-cm-long thin glass rod uniformly charged to 9.00 and a 10-cm-long thin plastic rod uniformly charged to - 9.00 are placed side by side, 3.90 apart. What are the electric field strengths to at distances 1.0 cm, 2.0 cm, and 3.0 cm from the glass rod along the line connecting the midpoints of the two rods?

2. Relevant equations

E=kq/r^2

3. The attempt at a solution

I figured out E1. From getting E of left and right and then adding them together. But how do I find E2? or E3?
