If two charges q₁ and q₂ are separated with distance ' d ' and placed in a medium of dielectric constant K . What will be the equivalent distance between charges in air for the same electrostatic force ?

Options

  1. Ad K
  2. BK d
  3. C1.5 d K
  4. D2 d K

Correct answer

A. d K

Step-by-step solution

As. F (air)= F (medium) 1 4 ₀ q ₁ q ₂ ~d _ air ^2 = 1 ~K 1 4 ₀ q ₁ q ₂ ~d ^2 ~d _ air = d K
