Question: To practice Problem-Solving Strategy 17.2 Electric field calculations Three identical particles, q1, q2, and q3, each with charge q = 5.00 μC , are placed along a circle of radius r = 2.00 m at angles 90, 180, and 270 degrees from the positive x axis, respectively. What is the resultant electric field at the center of the circle, point O? All angles are To practice Problem-Solving Strategy 17.2 Electric field calculations Three identical particles, q1, q2, and q3, each with charge q = 5.00 μC , are placed along a circle of radius r = 2.00 m at angles 90, 180, and 270 degrees from the positive x axis, respectively. What is the resultant electric field at the center of the circle, point O? All angles are measured counterclockwise from the positive x axis. What would the magnitude E of the electric field at point O be if only particle q2 were present?coulomb.
