Two 0.09 pith balls are suspended from the same point by threads 40 long. (Pith is a light insulating material once used to make helmets worn in tropical climates.) When the balls are given equal charges, they come to rest 19 apart.
What is the magnitude of the charge on each ball? (Neglect the mass of the thread.)
q = C
