2019-05-10 Selkin TPHYS 121 122-03-01-b A positively-charged ring surrounds a negatively charged disc (both objects are insulators). The ring has a total charge of +5.0 nC; the disc has a total charge of-5.0 nC. The ring-disc assemblage has a radius of 0.2m, and the ring's thickness is negligible compared to the radius. Find the electric field 3 mm from the center of the assemblage. +5.0 nC pist 5.0 nC 3.0 mm z 10)
