Question

A circular plastic rod with uniform charge q produces an electric field of magnitude e at the center of curvature (at the origin). in figs. 22-28b, c, and d, more circular rods,each with identical uniform charges q,are added until the circle is complete.a fth arrangement (which would be labeled
e.is like that in d except the rod in the fourth quadrant has charge q.rank the ve arrangements according to the magnitude of the electric eld at the center of curvature,greatest rst

Answer 1

Electric eld at the center of
