$\mathrm{q}_{5}=5 \mathrm{\,C} \times \mathrm{V}=5 \mathrm{\,C} \times 10 \Rightarrow \mathrm{q}_{5}=50 \mathrm{\,C}$

$\mathrm{V}_{\mathrm{AB}}=6 \mathrm{\,V}$ and $\mathrm{V}_{\mathrm{BC}}=4 \mathrm{\,V}$

So change on $C$ is $q_{1}=C \times 6=6 \,C$

$\mathrm{q}_{2}=2 \mathrm{C} \times 4=8 \mathrm{\,C}$

$\mathrm{q}_{3}=3 \mathrm{C} \times 6=18 \mathrm{\,C}$

$q_{4}=4 C \times 4=16 \mathrm{\,C}$

$\therefore $ $\mathrm{q}_{1}: \mathrm{q}_{2}: \mathrm{q}_{3}: \mathrm{q}_{2}: \mathrm{q}_{5}=6 \mathrm{C}: 8 \mathrm{C}: 18 \mathrm{C}: 16 \mathrm{C}: 50 \mathrm{C}$

$=3: 4: 9: 8: 25$
