When a Na ion and a CI ion are placed in air a force F acts between them when they are separated by a distance of 1 cm from each other the permittivity of air and the dielectric constant of water are ε0 and K respectively When a piece of salt is placed in water then the force between Na+ and CI- ions separated by a distance of 1 cm will be
In an AC circuit a resistance of R ohm i connected in series with an inductance L if phase angle between voltage and current be 45o the value of inductive reactance will be
