Two positively charged identical spheres separated by a distance 'd' exert some force (F) on each other when they are kept in air. If both the spheres are immersed in a liquid of dielectric constant 5 , the force experienced by each is (All other parameters are unchanged.)

Options

  1. A5 ~F
  2. BF 3
  3. CF 4
  4. DF 5

Correct answer

D. F 5

Step-by-step solution

The ratio of force when the medium is changed will be: F ₁ ~F ₂ = 1 k Here, k =5 , Therefore, the force experience by each will be F 5
