There are 8 drops of a conducting fluid. Each has radius r and they are charged to potential 1 volt. They are then combined to form a bigger drop. Find potential of big drop in volt.

Answer:

Solution:

For each small drop: $V = \frac{k q}{r} = 1$ volt.

Bigger drop: charge 8q, radius 2r:

$V^{'} = \frac{k ( 8 q )}{2 r} = 4 (\frac{k q}{r}) = 4 volt$ . Answer 4.
