 # we know the force between the two charges in any medium is 1/K times the force between the same in air. where K is dielectric constant. if dielectric constant of metal is infinity then the force between the two charges when placed inside the metal should be zero. if so then the charges should not experience any electrostatic force between them, but in real practice when two charges are kept inside the metal they move as far as possible ie they move to the surface of the conductor. which contradicts the fact that the dielectric constant of metal is infinity. really k=0 or k=infinity for metal???????

actually,

 the force between the two charges in any medium is 1/er times the force between the same in air. er is the relative di electric constant.also er=k.relative dielectric constant can never be zero since it is relative w.r.t vaccum. so k=o or k=infinity iss not possible.

if k is not 0 or k is not infinity then what is the value of dielectric constant of a metal.
