Item 3 < 3 of 12 > 1 Review Two point charges are placed on the x axis. (Figure 1)The first charge, q1 = 8.00 nC, is placed a distance 16.0 m from the origin along the positive x axis; the second charge, 92 = 6.00 nC, is placed a distance 9.00 m from the origin along the negative x axis. Part A Calculate the electric field at point A, located at coordinates (0 m, 12.0 m). Give the x and y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant figures. View Available Hint(s) Hint 1. How to approach the problem Find the contributions to the electric field at point A separately for nC and nC, then add them together (using vector addition) to find the total electric field at that point. You will need to use the Pythagorean theorem to find the distance of each charge from point A. Hint 2. Calculate the distance from each charge to point A Hint 3. Determine the directions of the electric fields Hint 4. Complete previous hint(s) Hint 5. Complete previous hint(s) IVO AQ R O 2 ?
