1. The problem statement, all variables and given/known data 8 Charged drops of water each of radius 1 mm and having a charge of 10^(-10) Coloumbs are combined to form a bigger drop.Determine the potential of the bigger drop. 2. Relevant equations Does the radius becomes 4*10^(-3)m,when it combines? Does the charge sum up to 9*10^(-10)? 3. The attempt at a solution Used the formula -V=9*10^(9)*Q/r Got the ans as 1800 V.
