Question

Two identical thin metal plates has charge $\mathrm{q}_1$ and $\mathrm{q}_2$ respectively such that $q_1>q_2$. The plates were brought close to each other to form a parallel plate capacitor of capacitance C. The potential difference between them is :

Select the correct option:

$\frac{\left(q_1+q_2\right)}{c}$

$\frac{\left(q_1-q_2\right)}{C}$

$\frac{\left(q_1-q_2\right)}{2 C}$

$\frac{2\left(q_1-q_2\right)}{C}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

electric field between plates $$ \begin{aligned} & E=\frac{q_1-q_2}{2 A \epsilon_0} \\ & V=E d=\frac{q_1-q_2}{2 A \epsilon_0} d \\ & V=\frac{q_1-q_2}{2 C} \end{aligned} $$
