Question

9. In a parallel plate uncharged capacitor, by transferring 1.25 x 1013 electrons from one plate to the other a potential difference of 4 V is produced. Find the capacitance of the capacitor ​

Answer 1

Answer:

Based on the symmetry of charges at equilibrium condition, +4Q will divide into −2Q each. Similarly−2Q will divide into −Q each.

Effictively capacitance=C+C=2C

So, the final potential difference =

2C

2Q−(Q)

=

2C
