The relation between the breakdown voltage V and the thickness t of the dielectric -

The relation between the breakdown voltage V and the thickness t of the dielectric is given as V =​​ At2/3 where A is a constant which depends on the nature and thickness of the medium. This statement is known as

A) Baur's law.
B) Coulomb's law.
C) none of these answers
D) Gauss's law.

Answer: A
