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

Assertion (A): Two parallel metal plates having charge +Q and -Q are facing at a distance between them. The plates are now immersed in kerosene oil and the electric potential between the plates decreases. Reason (R ): Dielectric constant of kerosene oil is less than 1.

Two metal plates having charges Q_1-Q face each other at some separation and are dipped into an oil tank .If the oil is pumped out, the eletric field between the plates will

An isolated charged capacitor with vacuum between its plates is dipped into an oil tank. If the oil is pumped out, the electric field between the plates of capacitor will

Two large metal plates each of area 1 m^(2) are placed facing each other at a distance of 5 cm and carry equal and opposite charges on their faces. If the electric filed between the plates is 1000 NC^(-1) , find the charge on each plate.
