Answer:
[tex]E=1.58*10^6N/C[/tex]
The direction is toward the negative x axis i.e the Rod
Explanation:
From the question we are told that:
Length [tex]L=14.0cm[/tex]
Total charge [tex]q=-22.0\muC[/tex]
Distance [tex]d=36cm=>0.36m[/tex]
Generally the equation for Electric Field is mathematically given by
[tex]E=\frac{kq}{d^2}[/tex]
Since Magnitude of E is at 36cm away from center
[tex]E=\frac{kq}{d^2-(L/2)^2}[/tex]
[tex]E=\frac{9*10^9*(22*10^6)}{0.36^2-(0.14m/2)^2}[/tex]
[tex]E=1.58*10^6N/C[/tex]
Therefore with Charge Bearing the Negative sign the direction is toward the negative x axis i.e the Rod
