I Electric field between two oppositely charged rods?

  1. Feb 7, 2017 #1
    I just need to know if I am going about this problem in the right way. The question is

    A 10-cm-long thin glass rod uniformly charged to 10.0 nC and a 10-cm-long thin plastic rod uniformly charged to - 10.0 nC are placed side by side, 4.10 cm apart. What are the electric field strengths E1 to E3 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?​

    Is this a continuous charge distribution problem? If so, do I need to find the electric field at each point due to both rods, or will finding the electric field due to one rod suffice? Thanks.
