Question: Five equal masses M are equally spaced on the arc of a semicircle of radius R as in Figure. A mass m is located at

Five equal masses M are equally spaced on the arc of a semicircle of radius R as in Figure. A mass m is located at the center of curvature of the arc.

(a) If M is 3 kg, m is 2 kg, and R is 10 cm, what is the force on m due to the five masses?

(b) If m is removed, what is the gravitational field at the center of curvature of thearc?
