You measured the force between two charged pith balls where thepith balls were of the same size and mass. Your assumption was thatthe charge on the balls was the same. Now, you charge the balls sothat they hang a distance r apart. Then you step out to get a drinkof water, and when you return, you find the distance between thepith balls is half what it was before you got a drink. In terms ofthe length L, the charge Q, and the original angle θ, find the newcharge on the pith balls and the new angle at which they hang.
