There is a uniform charge distribution of 790 10-8 cm, Ask an Expert

Academics

There is a uniform charge distribution of ?= 7.90 * 10^-8 C/m along a thin wire of length l=5.58 cm. The wire is then curved into a semicircle that is centered about the origin, so the radius of the semicircle is R=l/p. Find the magnitude of the electric field at the center of the semicircle.
