A line of positive charge is formed into a semicircle of radius R = 57.1 cm.

The charge per unit length along the semicircle is described by the expression lambda = lambda0cosθ. The total charge on the semicircle is 13.7 µC. Calculate the total force on a charge of 2.82 µC placed at the center of curvature.
