Hi, I am having trouble understanding this scenario. Here the charge per unit length on this thin rod shown below is λ. What is the electric field at the point P? Considering the electric field at p is dq = λdx, as a small segment dx of the rod containing the charge . How would I find the net field by integrating over the length of the rod? Any help would be greatly appreciated :)
