Q. 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

JIPMERJIPMER 2013Electric Charges and Fields

Solution:

The electric field between two charged parallel plates placed in air is
E=σε0=Qε0A ...(i)
When the parallel plates are immersed in kerosene oil tank of dielectric constant K, the electric field between the plates is
E=σKε0=QKε0A=EK (Using (i))
EE=1K
As K>1, so E<E
