Q. A capacitor with air as the dielectric is charged to a potential of $100\ volts.$ If the space between the plates is now filled with a dielectric of dielectric constant $10,$ the potential difference between the plates will be
A) $1000\ volts$
B) $100\ volts$
C) $10\ volts$
D) Zero
Explanation
(c) New potential difference $= \frac{V}{K} = \frac{100}{10} = 10V$
