Homework Statement
Two thin glass rods are placed side by side 4.70 cm apart as shown in the diagram below. They are each 11.3 cm long and are uniformly charged to +10.4 nC .
Answer the questions below regarding the electric field along a line which is drawn through the middle of the two glass rods (labeled Bisector in the diagram).

Homework Equations
*See attached file for relevant equations*
The Attempt at a Solution
Length = 0.113 m
λ = 9.20×10^−8 C/m
Eo = 8.85*10^-12
r1 = 0.037m
r2 = 0.01m
Using the attached equation... I got -1.21*10^5 N/C ... the magnitude of the field is 1.21*10^5 N/C
I know this is wrong but I am confused as to why?
