Question
Two parallel metal plates having charge + Q and - Q face other at a certain distance between them. If the plates are now dipped in kerosene(K>1) oil tank, the electric field between the plates will ?
Options
A.become zero
B.increase
C.decrease
D.remain same
Solution
Electric field between two parallel plates placed in vaccum is given by
E =
In a medium of dielectric constant K, E′ =
For kerosene oil K > 1 ⇒ E′ < E
E =
In a medium of dielectric constant K, E′ =
For kerosene oil K > 1 ⇒ E′ < E
