A parallel plate capacitor with plate separation $\displaystyle 5$ mm is charged up by a battery. It is found that on introducing a dielectric sheet of thickness $\displaystyle 2$ mm , while keeping the battery connections intact, the capacitor draws $\displaystyle 25 \%$ more charge from the battery than before. The dielectric constant of the sheet is $\displaystyle \_\_\_\_$.
