Two identical brass balls mounted on wooden posts initially have different amounts of charge, one at +6 uC and the other at +10 uC. The balls are allowed to touch and then are separated again. What is the final charge on each ball? Group of answer choices: 8 uC, 16 uC, 6 uC, 10 uC.

There are three identical metal balls A, B, and C, where ball A has an excess of - charge (-4 C), while both balls B and C are neutral. If ball A comes in contact with ball B momentarily, and then ball B comes in contact with ball C momentarily, what will be the charge on each of the balls afterwards?

Two balls have the same mass, $0.9935 \mathrm{~kg}$, and the same charge. They hang from the ceiling on strings of identical length, $\ell=1.235 \mathrm{~m}$, as shown in the figure. The angle of the strings with respect to the vertical is $22.35^{\circ}$ What is the charge on each ball?
