Question

Two parallel metal plates having charges $+Q$ and $-Q$ face each other at a certain distance between them. If the plates are now dipped in kerosene oil tank, the electric field between the plates will

Professor PC Thomas Classes · Answer

Electric field between two parallel plates placed in vacuum is given by $E=\frac{\sigma}{\varepsilon_{0}}$
In a medium of dielectric constant $K, E^{\prime}=\frac{\sigma}{\varepsilon_{0} K}$
For kerosene oil $K>1 \Rightarrow E^{\prime}<E$
