Two identical point charges (q = +7.30 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.310 m. A test charge (qo = -5.90 x 108 C), with a mass of 7.10 x 10-8 kg, is released from rest at one of the corners of the square. Determine the speed of the test charge when it reaches the center of the square. 90
