Electrostatics 5 Question 21
23. In the given circuit, a charge of $+80 \mu \mathrm{C}+80 \mu \mathrm{C}$ o is given to the upper plate of the $4 \mu \mathrm{F}$ capacitor. Then in the steady state, the charge on the upper plate of the $3 \mu \mathrm{F}$ capacitor is
(2012)
(a) $+32 \mu \mathrm{C}$
(b) $+40 \mu \mathrm{C}$
(c) $+48 \mu \mathrm{C}$
(d) $+80 \mu \mathrm{C}$
Show Answer
Answer:
Correct Answer: 23. (c)
Solution:
- Between $3 \mu \mathrm{F}$ and $2 \mu \mathrm{F}$ (in parallel), total charge of $80 \mu \mathrm{C}$ will distribute in direct ratio of capacity.
