The figure shows an uneven arrangement of electrons (e) and protons (p) on a circular arc of radius \( r-2.05 \mathrm{~cm} \), with angles \( \theta_{1}-24.00^{\circ} \). \( \theta_{2}=53.0^{\circ}, \theta_{3}-38.0^{\circ} \), and \( \theta_{4}=22.0^{\circ} \). What are the (a) magnitude and (b) direction (relative to the positive direction of the \( x \) axis) of the net electric field produced at the center of the arc? (a) Number Unit (b) Number Unit
