Electrostatics Question 643
Question: Two capacitors $ C _{1} $ and $ C _{2} $ are charged to 120 V and 200 V respectively. It is found that by connecting them together the potential on each one can be made zero. Then
Options:
A) $ 3C _{1}=5C _{2} $
B) $ 3C _{1}+5C _{2}=0 $
C) $ 9C _{1}=4C _{2} $
D) $ 5C _{1}=3C _{2} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ 120C _{1}=200C _{2} $
$ 6C _{1}=10C _{2} $
$ 3C _{1}=5C _{2} $
