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:

Options

  1. A-12 C
  2. B+12 C
  3. C-18 C
  4. D+18 C

Correct answer

D. +18 C

Step-by-step solution

As given in the figure, 6 F and 4 F are in parallel. Now using charge conservation Charge on 6 F capacitor = 6 6+4 30=18 C Since charge is asked on right plate therefore is +18 C
