1. Two gilded pith balls having a mass of 100 mg each are suspended in air by silkthreads 30 cm long attached to a common point. When the balls are given equal charges, they are repelled to a distance of 18 cm from each other. What is the charge on each ball? (Answer: 3.09 statcoulomb). Write the Given, FBD or diagram, and the solution.
