 (6) [5 points] Charged pith balls hang from strings and repel

(6) [5 points] Charged pith balls hang from strings and repel each other as shown in the photograph and as was demonstrated in lecture. Assume the pith balls have equal mass and equal positive electric charge. The mass of one pith ball is 0.30 grams. The length of one string is 6.0 cm. The half-opening angle is 10\". Estimate the number of missing electrons on one pith ball. Your work should include a free body diagram, and you are welcome to use the small angle approximation
