Three nonconducting strips are bent to form arcs and, when assembled, they form part of a circle of radius r-6.47 cm. The three strips have linear charge densities of -88.0 nC/m, 12-179 nC/m, and A-268 nC/m, respectively, and subtend angles of 60, 120, and 45°, respectively, at the center. λ₁ 120 λ₁ 2₂ (a) Determine the electric potential at the center of the circle of which the strips form a part TV (b) You use a fourth nonconducting strip to close the circle. What should be the linear charge density on this strip if the potential at the center of the circle is to be zero?
