Assume each oil drop consists of a capacitance of C. If combine n drops to form a bigger drop, then the capacitance of bigger drop C' would be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Let r and R be the radius of small drop and big drop respectively.
Capacitance of each oil drop is
As volume remains same
volume of 1 small drop = volume of 1 large drop
So, capacitance of large drop is
