Answer:
E=6.91 N/C
Step-by-step explanation:
Given that
Linear Charge density ,λ = 5 nC/m
Distance ,R= 13 m
We know that formula for long wire to find electric field
![E=(\lambda )/(2\pi \varepsilon _0R)](https://img.qammunity.org/2020/formulas/physics/high-school/f7gy1r7l0joj6q4iwq3crik8ocasi1s10v.png)
E=Electric field
R=Distance
εo=8.85 x 10⁻¹² C²/N.m²
λ=Linear Charge density
Now by putting the values
![E=\frac{5* 10^(-9)}{{2* \pi * 8.85* 10^(-12)* 13}}](https://img.qammunity.org/2020/formulas/physics/high-school/kjscjxdn5c50b3tnrfv1wjxmzf54ey216x.png)
E=6.91 N/C
Therefore the electric filed at distance 13 m will be 6.91 N/C
