A uniformly charged thin rod is bent into a semicircle of radius R = 0.800 m. Its charge per unit length is λ = 6.50 nC/m. Calculate the potential at the center of the semicircle, assuming that the potential at infinity is 0. Give the answer in unit of Volt (V). (answer should have at least 3 sig figs)
