Q. Between the plates of a parallel plate condenser there is $1mm$ thick paper of dielectric constant 4. It is charged at $100\ volt.$ The electric field in $volt/metre$ between the plates of the capacitor is
A) 100
B) 100000
C) 25000
D) 4000000
Explanation
(b) $E = \frac{V}{d} = \frac{100}{10^{- 3}} = 10,0000\ V/m$
