Find the electric field at the origin of the x,y-plane for charge distributions (a) and (b), see the figures shown below. The field is produced (a) by a thin half-circle with a radius of 22 cm and the linear charge density k = 32 pC/cm and (b) by a thin quarter-circle with the same radius and the linear charge density K = -32 pC/cm.
