In Figure (a) a particle of charge + Q produces an electric field of magnitude E _part, at point P, at distance

R from the particle R from the particle, in figure (b) that same amount of charge is spread uniformly along a circular arc that has radius R and subtends an angle θ. The charge on the arc produces an electric field of magnitude E _arc at its center of curvature P For what value of θ does E_arc = 0.500E_part?
