2 ator x: ) 2 ick 14. (5 points) Four charged particles are arranged in a square with a side length L = 10 6 m. Two of the particles each have a positive charge q = 3.2 x 10-19 Coulombs, while the other two each have a negative charge -q = -3.2 x 10 19 Coulombs. Using the axes shown (you may assume the origin is at the center of the square), calculate the net electromagnetic force exerted on the particle in the lower left-hand corner. T1
