A square with sides of length 0.4 meters has 8 charges on it. Four charge of +q, +q, +q, and -q (same amount of charge for three and one has an opposite sign) are placed in the corners and four charges of twice the magnitude of -2q, -2q, -2q, and +2q are placed halfway in the middle of the sides. Here q = 9 micro-coulombs. (In other words, -q = -9 micro-coulombs and +2q is twice 9 micro-coulombs.) A ninth charge of -6 micro-coulombs with a mass of 4 kg is placed at the center. When the charge is very far away from the other charges, how fast is the ninth charge moving in m/s? Ignore gravity.
