The problem involves 27 identical mercury drops, each charged to a potential of 10 volts. When combined into one larger drop, the total charge remains constant, and the potential can be calculated using Gauss's Law. The final radius of the larger drop can be determined, allowing for the calculation of the new potential based on the total charge and the radius of the combined drop.

Infinitum said:Each mercury drop can be assumed to be a conducting sphere(because it's a metal) and you can find their potential in terms of Q and r with the help of Gauss Law. Now, when these 27 drops are combined, the final radius R can be found, and the total charge, thereby giving you the potential of the bigger drop.
