ball and call that "0," and use the scale to measure the distance from the left pith ball to the right pith ball, and call that "r." Once these are values are measured use the formula below to determine the electric force, "F elect," weight, "W," tension, "T," given charge, "Q ,", and calculated charge, "Q." The gravitational attraction force or "Fray," is considered negligible and will not be calculated yet.
