Three narrow concentric rings of radii 41 mm, 71 mm, and 94 mm are centered about the origin along the y - axis, with the axis of symmetry of each ring oriented along the y axis. The total charge on the inner ring is 1.8 µC, that on the middle ring is -1.0 µC, and that on the outer ring is 1.2 µC. What is the electric field magnitude (in N/C) at (0, 90 mm, 0)? Type in your answer in scientific format correct to one decimal place. Use a period for the decimal point. Do not use a comma. Scientific format is written as for eg. 1.2*10^8 to represent 1.2 × 10° Do NOT include units in your answer. Hint: You may assume that the electric field at a point y on the y-axis from a ring centered about the y-axis is given by Qu E (y) = k- (R²+y²){ where R is the radius of the ring and Q is the total charge on the ring in Coulombs.

Question
Transcribed Image Text:Three narrow concentric rings of radii 41 mm, 71 mm, and 94 mm are centered about the origin along the y - axis, with the axis of symmetry of
each ring oriented along the y axis. The total charge on the inner ring is 1.8 µC, that on the middle ring is -1.0 µC, and that on the outer ring is 1.2
µC. What is the electric field magnitude (in N/C) at (0, 90 mm, 0)?
Type in your answer in scientific format correct to one decimal place. Use a period for the decimal point. Do not use a comma. Scientific format is
written as for eg. 1.2*10^8 to represent 1.2 × 10° Do NOT include units in your answer.
Hint: You may assume that the electric field at a point y on the y-axis from a ring centered about the y-axis is given by
E (y) = k– Qy
(R+y?)%
where R is the radius of the ring and Q is the total charge on the ring in Coulombs.
