Question

A thin rod with mass M = 5.85 kg is bent in a semicircle of radius R = 0.606 m (the figure below). (a) What is its gravitational force (both magnitude and direction) on a particle with mass m = 3.37×10-3 kg at P, the center of curvature? (b) What would be the force on the particle if the rod were a complete circle?
