Two identical point charges (q = +6.90 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.450 m. A test charge (q0 = -3.20 x 10-8 C), with a mass of 5.20 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.
