A flat ring (inner radius RO, outer radius 4R0) is uniformly charged. [Hint. The ring can be replaced with two oppositely charged superposed disks. ▼ Part A In terms of the total charge Q, estimate the electric field on the axis at point 0.02Ro from the center of the ring. Express your answer in terms of some or all of the variables Q, Ro, and the appropriate constants.
