Question 676: Electrostats & Capacitance

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

Accepted Answer

Electric field between two parallel plates placed in vacuum is given by
$$E = {\sigma  \over {{\varepsilon _0}}}$$
In a medium of dielectric constant K, $$E' = {\sigma  \over {{\varepsilon _0}}}$$
For kerosene oil K > 1   $$ \Rightarrow $$   E' < E
