Positive charge +Q is uniformly distrubted around a quarter circle of radius R in the 1st quadrant, and negative charge -Q is uniformly distributed around a quarter circle of radius R in the 4th quadrant. (a) Determine the x and y components of the electric field at the origin. Show all details of the setup and integration. You may use symmetry to reduce the number of integrals to be set up. (b) A positive point charge +q is placed at theorigin. Determine the x and y components of the electric froce at this point charge.
