A uniformly charged rod of length L is bent into an arc of radius R. Total charge on the rod is Q. This is similar to the arc problem we considered in class. R * P (a) Find the angle in radians, 0, subtended by the arc and the linear charge density A in terms of Q, L and R. See the exercises and the hints and guide at the end of the homework for a reminder of the relationship between angle and arc length.
