Section B
Twenty-seven drops of same size are charged at 220 V each. They combine to form a bigger drop. Calculate the potential of the bigger drop.
Text Solution
Verified by ExpertsThe correct answer is:
NOT AVAILABLE
If each drop has a charge ‘ q ’ and radius ‘r’.
Then from conservation of charge, charge on the big
drop is nq = 27 q (n = 27)
from conservation of volume 

Now potential of the small drop 
Potential of the big drop.
