Asked by Allee

Two idencial point charges (q = 7.40 x 10^-6 C) are fixed at diagonally opposite corners of a square with sides of length 0.440m. A test charge (q = -2.30 x 10^-8 C), with a mass of 7.25 x 10^-8 kg, is released from rest at one of the empty corners of the square. Determine the speed of the test charge when it reaches the center of the square.
