2. In the figure below, two charges spheres have equal masses of 2.56 grams. x = 2.5 cm, L = 13 cm, and D = 22 cm. L D Use the information provided to calculate the angle each string makes with the vertical, the tension in each string, and the magnitude of the charge on each sphere. In the figure above, the charges repel each other. They are both positive or both negative. Historically, how did Benjamin Franklin decide what charge was positive? (Use Google's help as needed.)
