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 12.5 cm and the linear charge
density K = 18.5 pC/cm and (b) by a thin quarter-circle with the same radius and the linear charge density
K = -18.5 pC/cm.
K>0
