Electrostatics Question 594
Question: A potential difference of 300 volts is applied to a combination of 2.0mF and 8.0mF capacitors connected in series. The charge on the 2.0mF capacitor is [MP PMT 2000]
Options:
A) $ 2.4\times {{10}^{-4}} $ C
B) $ 4.8\times {{10}^{-4}} $ C
C) $ 7.2\times {{10}^{-4}} $ C
D) $ 9.6\times {{10}^{-4}} $ C
Show Answer
Answer:
Correct Answer: B
Solution:
In series combination charge Q is same. So charge on 2mF capacitor is $ Q=C _{eq}V=( \frac{2\times 8}{2+8} )\times 300\times {{10}^{-6}} $
$ =4.8\times {{10}^{-4}}C $
