In the diagram, the area of each plate is $2 \mathrm{~m}^2$ and $\mathrm{d}=2 \times 10^{-3} \mathrm{~m}$. An electric charge of $8.85 \times 10^{-8} \mathrm{C}$ is given to the plate ' $\mathrm{Q}$ '. Then the potential of $\mathrm{Q}$ is

• A

  $13 \mathrm{~V}$
• B

  $10 \mathrm{~V}$
• Correct answer
  C

  $\frac{20}{3} \mathrm{~V}$
• D

  $8.85 \mathrm{~V}$

Hence, the correct answer is option: 'C'.
