In a pith ball experiment, the two pith balls are at rest. the ball on the left has a charge of 6.8 x 10-6 c, the ball on the right has a charge of 10.5 x 10-6 c. each has a mass of 45 grams, they are 0.50 m apart, and the angle between each string and a vertical line is θ = 27.72°. what are the values for the magnitudes of the tension in each string, t, the gravitational force, fg, and the electrostatic force, fq?
