please awnser

Three narrow concentric rings of radii 44 mm, 67 mm, and 90 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 1.6 uC, that on the middle ring is -1.5 µC, and that on the outer ring is 1.5 uC. What is the electric field
magnitude (in N/C) at (0, 86 mm, 0)?
Type in your answer in scientific format correct too 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 x 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) = kQu
(R +y?) ?
where R is the radius of the ring and Q is the total charge on the ring in Coulombs.
