Electric Field at Various Points Between Two Charged Rods

Homework Statement


Two questions:

One problem asked me to calculate the Electrical Field at points 1 (1cm from the + rod),2 (2 cm from the positive rod), and 3 (3 cm from the positive rod) between a +10 nC rod and a -10 nC rod (in the middle in the vertical direction). I found that positions 1 and 3 were the same, which was whatki I expected, but I thought it was weird that the field in the very center (the rods are 4 cm apart), so at 2 cm from the positively charged rod, the field was LESS than in the other two positions. This seemed counterintuitive. Did I make a mistake?



Homework Equations



Erod=1/(4pi[tex]\epsilon[/tex]0))*[tex]\left|Q\right|[/tex]/(d*(d2+(L/2)1/2)

(Epsilon shouldn't be an exponent)
