The capacity of parallel plate condenser is 5 F . When a glass plate is placed between the plates of the condenser, its potential difference reduces to 1 / 8 of the original value. The magnitude of relative dielectric constant of glass is

Options

  1. A4
  2. B6
  3. C7
  4. D8

Correct answer

D. 8

Step-by-step solution

Given, C=5 F =5 10⁻⁶ ~F Initial potential =V When glass plate of dielectric constant K is introduced between the plates of capacitor, then potential difference is aligned & V^ & = V 8 & K & = V V^ = V V / 8 & K & =8 aligned
