V Part A Charge Q is uniformly distributed along a thin, flexible rod of length L. The rod is then bent into the semicircle shown in the figure (Figure 1). Find an expression for the electric field E at the center of the semicircle. Hint: A small piece of arc length As spans a small angle A0 = As / R, where R is the radius. Express your answer in terms of the variables Q, L, unit vectors i, j, and appropriate constants.
