The figure shows an uneven arrangement of electrons (e) and protons ( \( \mathrm{p} \) ) on a circular arc of radius \( r=2.10 \mathrm{~cm} \), with angles \( \theta_{1}=26.0^{\circ} \), \( \theta_{2}=41.0^{\circ}, \theta_{3}=30.0^{\circ} \), and \( \theta_{4}=32.0^{\circ} \). 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
