The figure shows an uneven arrangement of electrons (e) and protons (p) on a circular arc of radius r = 2.40 cm, with angles 01 = 20.0°, 02 = 51.0°, 03 = 34.0°, and 04 = 24.0°. 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? In the figure the four particles are fixed in place and have charges 91 = 92 = 4e, 93 = 3e, and 94 = -12e. Distance d = 4.26 um. What is the magnitude of the net electric field at point P due to the particles? 42
