Part A Three narrow concentric rings of radii 50 mm, 70 mm, and 90 mm are centered about the origin, with the axis of symmetry of each ring oriented along the y axis. The charge on the inner ring is 1.7 C, that on the middle ring is -1.3 C, and that on the outer ring is 1.6 μC What is the electric field magnitude at (0, 100 mm, 0)? Express your answer with the appropriate units. ЦА ? E = Value Units Submit Request Answer Part B What quantity of charge must be placed at (0, -100 mm, 0) to make the electric field magnitude zero at the position calculated in the previous part?
