Question 1 of 10 - /1 View Policies Current Attempt in Progress - d- + + + 9 -9 -9 + 9 Electric quadrupole. The figure shows an electric quadrupole. It consists of two dipoles with dipole moments that are equal in magnitude but opposite in direction. What is the value of E on the axis of the quadrupole for a point P a distance z from its center (assume z > > d)? Take Q = 2qd (which is known as the quadrupole moment of the charge distribution.) NOTE: Express your answer in terms of Q and z, using co when needed. E =Question 3 of 10 - /1 E .. . View Policies Current Attempt in Progress The figure shows three circular arcs centered at the origin of a coordinate system. On each arc, the uniformly distributed charge is given in terms of Q = 2.65 UC. The radii are given in terms of R = 10.1 cm. What are the (a) magnitude and (b) direction (relative to the positive x direction) of the net electric field at the origin due to the arcs? +90 + 3R -40 2R R (a) Number Units (b) Number i Units eTextbook and Media Hint Save for Later Attempts: unlimited Submit AnswerQuestion 4 of 10
