Given:
Potential difference between capacitor plates = 2.6 V
Dielectric constant of paper , K = 3.7
Solution:
When air is filled, let the potential difference between capacitor plate be V'
Now, after being disconnected from the battery, the charge stored in the capacitor will remain constant
And when dielectric is introduced between the capacitor plates, the potential difference will be reduced by k times a:
V = 
Therfore, V' = KV = 3.7 × 2.6 = 9.62 V
The resulting potential difference of the capacitor, V' = 9.62 V

Antecedent _architect_.
From the dictionary:
Antecedent: a word or phrase that a pronoun refers back to:
In the sentence "He picked a book off the shelf and handed it to Sally", "book" is the antecedent of "it
"In" is a preposition.
·In their exploration
·in their sacrifice
"Of" is a preposition.
·of the world
"To" is a preposition.
·to feel as one
