In lab,

In lab, suppose that we take two small aluminum spheres of 1.00 gram each and hang them from a common support point with long non-conducting
threads of equal length. While they are touching, we put some negative charge on the two spheres. Suppose that the two spheres share the charge equally.
When things settle down, the spheres repel and settle down to hang as shown in the figure below. The horizontal distance between the spheres is 17.89
cm. As shown by the grid, this is the same as the vertical distance between the support and the spheres. What is the angle each of the threads makes at the support, measured from the vertical direction?
x 0 Draw a free body diagram and use it along with Coulomb's law and Newton's second law to answer the following questions. Use 9 = 9.6 kag,
e = 1.602 X 10‘19 C and k = 8.99 X 109 in SI units. What is the magnitude of the tension in one of the threads supporting the aluminum spheres?
N What is the magnitude of the net charge on one of the aluminum spheres? (You can enter your answer using scientific notation, e.g., 0.00025 would be
2.5e-4.) xC How many more electrons than protons are there on one of the aluminum spheres? (You can enter your answer using scientific notation, e.g., 25,000 would
be 2.5e4.)
