Two plates are 2cm apart, a potential difference of 10 volt is applied between them, the electric field between the plates is

Two plates are 2cm apart, a potential difference of 10 volt is applied between them, the electric field between the plates is

Two plates are 1.5 cm apart, and a potential difference of 7.5 volt is applied between them, the electric field between the plates is

Two parallel plates have equal and opposite charge. When the space between them is evacuated, the electric field between the plates is 2xx 10^(5) V/m. When the space is filled with dielectric, the electric field becemes 1xx10^(5) V/m. The dielectric constant of the dielectric material is
