ogress The figure shows an uneven arrangement of electrons (e) and protons (p) on a circular arc of radius r = 1.75 cm, with angles 01 = 24.0', 02 = 41.0', 03 = 35.0', and 04 = 22.0. 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? P X
