A positive point charge +Q is placed at a distance d from an infinite line of charge with charge density +λ as shown. Point A is located at a distance 2d to the right of the point charge +Q as shown.
Calculate the magnitude AND direction (angle θ respect to the x-axis shown) of the net electric field at point A for λ = 1.2 nC/m, Q = 2.5 nC, d = 1.5 m.
