The figure below shows a rod bent at an angle 0. The horizontal part of the rod has length L and the other slanted part has semi-infinite length (so that its top end extends to infinity), and the bent rod carries a uniform charge per length A. O The uniform rod bent at the angle (indicated) and point P is the small circle Determine (in terms of ke, A, L and 8) an expression for the magnitude of the electrostatic field at point P, which is directly to a right of the horizontal piece a distance L from the right end of this piece. You should place your final answer in the form ke|A| E(P) = -(0) 2L where f(0) is a function of 0 that your must determine. 13
