There is a line of negative charge (-Q) along the y axis (from 0 to L). There is a line of positive charge (+Q) along the x-axis (from 0 to L).
A) Find the electric field at the point (L/2, L/2). Sketch the direction of the field at this point on a diagram of the situation.
B) Find the potential at the point (L/2, L/2).
