Two identical point charges (q = +5.80 x 10-6 C) are fixed atopposite corners of a square whose sides have a length of 0.320 m.A test charge (q0 = -7.90 x 10-8 C), with a mass of 6.20 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 centerof the square.
