In the figure shown below, the charge on the left plate of the 10F capacitor is -30C. The charge on the right plate of the 6F capacitor is:

In the figure shown below, the charge on the left plate of the 10F capacitor is -30C. The charge on the right plate of

Options

A $-12 \mu \mathrm{C}$
B $+12 \mu \mathrm{C}$
C $-18 \mu \mathrm{C}$
D $+18 \mu \mathrm{C}$

Correct answer

D. $+18 \mu \mathrm{C}$

Step-by-step solution

In the figure shown below, the charge on the left plate of the 10F capacitor is -30C. The charge on the right plate of

As given in the figure,

6 \mu \mathrm{F}

and

4 \mu \mathrm{F}

are in parallel. Now using charge conservation Charge on

6 \mu F

capacitor

=\frac{6}{6+4} \times 30=18 \mu C

Since charge is asked on right plate therefore is

+18 \mu C
