Two foam blocks, each with a charge of 8 microcoulombs (1 µC = 10-6 C), are both held in place 8 cm apart in the east-west direction. A foam ball with a charge 38 µC is placed 55 cm north of the foam block on the west side. Then, the ball is released, and it moves as a result of the electrostatic force produced in this system. Draw a diagram of this system, and label the relevant objects, quantities, and force vectors before the ball is released.
