A galvanometer G of $$2\Omega$$ resistance is connected in the given circuit. The ratio of charge stored in $$C_1$$ and $$C_2$$ is
step 1: steady state idea
capacitors act as open circuits
so only resistors + galvanometer (2 Ω) matter
step 2: find equivalent resistance
the network reduces to:
4 Ω + 2 Ω + 6 Ω = 12 Ω
step 3: current
$$I=\frac{6}{12}=0.5\text{ A}$$
step 4: potential distribution
drop across 4 Ω:
$$V=0.5\times4=2\text{ V}$$
drop across 2 Ω:
$$V=0.5\times2=1\text{ V}$$
drop across 6 Ω:
$$V=0.5\times6=3\text{ V}$$
step 5: capacitor voltages
from node potentials:
• voltage across $$C_1$$ = 3 V
• voltage across $$C_2$$ = 4 V
step 6: charges
$$q_2=C_2V_2=6\mu F\times4=24\mu C$$
$$q_1=C_1V_1=4\mu F\times3=12\mu C$$
