Two identical point charges (q=+4 x 10^-6 C) are fixed at opposite sides of a square of side 0.61 m. A test charge (qo = -7.8 10^-8 C) with mass of 3.70 x 10^-8 kg, is released from rest at one of the corners if the square. Determine the speed of the test charge when it reaches the center of the square
