A line of positive charge is formed into a semicircle of radius R = 40.0 cm, as shown in the figure below. The charge per unit length along the semicircle is given by the expression = cos(0). The total charge on the semicircle is 13.0 C. Calculate the total force on a charge of 6.00 C placed at the center of curvature. magnitude direction N ---Select--- V R P x A line of positive charge is formed into a semicircle of radius R = 40.0 cm, as shown in the figure below.
