A line of positive charge is formed into a semicircle of radius R = 80.0 cm, as shown in the figure below. The charge per unit length along the semicircle is described by the expression ? = ?0 cos(?). The total charge on the semicircle is 14.0 µC. Calculate the total force on a charge of 4.00 µC placed at the center of curvature.
