Question details

Find an expression for the electric field E at the center of the semicircle. Hint: A small piece of arc length Δ8 spans a small angle Δθ-As /R, where R is the radius. Review Express your answer in terms of the variables Q. L, unit vectors i,j, and appropriate constants. Charge Q is uniformly distributed along a thin, flexible rod of length L. The rod is then bent into the semicircle shown in the figure (Figure 1).
