Two identical conducting very large plates $P_{1}and{P}_2$having charges +4Q and +6Q are placed very closed to each other at separation d. The plate area of either face of the plates is A. The potential difference between plates  $P_{1}and{P}_2$ is 

• A

  $V_{P_1}-V_{P_2}=\frac{Qd}{A{\epsilon }_0}$

• B

  $V_{P_1}-V_{P_2}=\frac{-Qd}{A{\epsilon }_0}$

• C

  $V_{P_1}-V_{P_2}=\frac{5Qd}{A{\epsilon }_0}$

• D

  $V_{P_1}-V_{P_2}=\frac{-5Qd}{A{\epsilon }_0}$
