Question

What is di electric constant?

Answer 1

$\huge Hello$$\huge friend,$

electric constant =8.85418782 × 10-12 m-3  kg-1 s4 A2


The symbol k is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 109 N.

the electric potential (V) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation: V = kQ/r, where k is a constant with a value of 8.99 x 109 N m2/.

Answer 2

The relative permittivity of a material is its permittivity expressed as a ratio relative to the permittivity of vacuum. Permittivity is a material property that affects the Coulomb force between two point charges in the material
