•29 Figure 22-47a shows a nonconducting rod with a uniformly dis- tributed charge +Q. The rod forms a half-circle with radius R and produces an electric field of magnitude Eare at its center of curvature P. If the arc is collapsed to a point at distance R from P (Fig. 22-47b), by what factor is the magnitude of the electric field at P multiplied? +Q P +Q P R FR- (a) (b)
