A spherical drop of capacitance 1 F is broken into eight drops of equal radius, then the capacitance of each small drop is

Options

  1. A1 2 F
  2. B1 4 F
  3. C1 8 F
  4. D8 F

Correct answer

A. 1 2 F

Step-by-step solution

As, the volume remains constant, so array ll & 4 3 R³=8 ( 4 3 r³ ) & R=2 r or r= R 2 Capacitance of spherical capacitor, C & =4 ₀ R & C R & C₁ C₂ = R r = 2 r r =2 C₂= C₁ 2 = 1 2 F array
