Plates of a parallel plate capacitor, having a potential difference 100 V applied across them, carry a surface charge density of 50 nC c m - 2 . Spacing between the plates is

Options

  1. A329 μ m
  2. B259 μ m
  3. C177 μ m
  4. D125 μ m

Correct answer

C. 177 μ m

Step-by-step solution

E = σ ε 0 Potential difference V = E d ∴ d = V E = 100 50 × 10 - 7 × 8.85 × 10 - 12 = 177 × 10 - 6   m = 177   μm
