Consider a wire of length $L$ with linear charge density $\lambda$.

Question

I am a new student, I know the concepts of electric field and it is difficult for me to solve this exercise. Could you help me with this exercise?

Consider a wire of length $L$ with linear charge density $\lambda$. Calculate the electric field at the points indicated in the following figure and make a diagram outlining the electric field at each point.

For practical purposes do $L = 1 m$, $\lambda = 1 c/m$. Scale the result by $9 \times 10^{-9}$.

Thanks in advance.
