Question

Three nonconducting strips are bent to form arcs and, when assembled, they form part of a circle of radius r= 5.97 cm. The three strips have linear charge densities of Az = 94.0 nC/m, 12 = -179 nc/m, and 13 = 268 nc/m, respectively, and subtend angles of 60°, 120°, and 45°, respectively, at the center. (a) Determine the electric potential at the center of the circle of which the strips form a part. 4383x What is the charge on each strip? Note that all points on a strip are at the same distance from the center. V (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? nC/m
