A parallel plate condenser is connected with the terminals of a battery. The distance between the plates is 6mm. If a glass plate (dielectric constant k = 9) of 4.5mm is introduced between them, then the capacity will become
Text Solution
Verified by ExpertsThe correct answer is:
C
$C \propto \frac{1}{d^2}$
⇒ ⇒ $\frac{C_{medium}}{C_{air}} = \frac{d}{d - t + \frac{t}{K}} = \frac{6}{6 - 4.5 + \frac{4.5}{9}} = \frac{6}{4.5} = \frac{6}{2} = 3$
