N small conducting liquid droplets, each of radius r, are charged to a potential V each. These droplets coalesce to form a single large drop without any charge leakage. Find the potential of the large drop.

Hello candidate,
The electrical potential of of any charged particle is given by the formula V= kq/radius. So, if all the liquid droplets conceal to form a bigger drop then the radius of that bigger law will change and so will its electric potential.
So, new radius= n^1/3*radius (r). So, the potential will remain same but overall charge will get changed because of the new radius.
Hope you found it helpful!!
