Electrostatics Question 88
Question: Two identical charged spherical drops each of capacitance C merge to form a single drop. The resultant capacitance is [AFMC 1993]
Options:
A) Equal to $ 2C $
B) Greater than $ 2C $
C) Less than $ 2C $ but greater than C
D) Less than C
Show Answer
Answer:
Correct Answer: C
Solution:
$ C’={{n}^{1/3}}C $
therefore $ C’={{2}^{1/3}}C $
therefore 2C < C’ > C
