##### Reference no: EM13544196

There is a uniform charge distribution of ? = 8.12 10-8 C/m along a thin wire of length L = 5.94 cm. The wire is then curved into a semicircle that is centered about the origin, so the radius of the semicircle is R = L/?. Find the magnitude of the electric field at the center of the semicircle.
