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
Options
(a) remain same
(b) become zero
(c) increases
(d) decrease
Correct Answer:
decrease
Explanation:
Electric field E = σ / ? = Q / A?
? of kerosine oil is more than that of air. As ? increases, E decreases.
