In the figure below are two uniformly charged disks of radiusRthat are very close toeach other (gap?R?R). The disk on the left has a charge of?Qleftand the disk on the right has a charge of+Qright(Qright is greater thanQleft). A uniformly charged thin rod of lengthLlies at the edge of the disks, parallel to the axis of the disks and centered on the gap. The rod has a charge of+Qrod. (Assume the+xaxisis to the right, and the+yaxisis upward.)
