Circulation of E-vector along a contour of complex shape. Figure 1.17 shows a contour consisting of two semicircular parts, of radii a and b (a < b), and two linear parts, each of length b−a, situated in free space. A point charge Q is placed at the contour center (point O). As in the previous MATLAB exercise, find numerically the line integral of the electric field intensity vector (due to Q) along the contour.
