16. If one of them is discharged, there would no electrostatic repulsion between the two balls and they would

both come to the position θ = 0, making contact with each other. A redistribution of the remaining

charge would then occur, with each of the balls getting q/ 2. Then they would again be separated due

to electrostatic repulsion, which results in the new equilibrium separation
