Four closed surfaces (S₁, S₂, S₃ ) and (S₄ ) together with charges (+q,-q ) and (-2 q ) are shown. Through which one of the surfaces the net flux is zero?

Options

  1. A(S₁ )
  2. B(S₂ )
  3. C(S₃ )
  4. D(S₄ )

Correct answer

B. (S₂ )

Step-by-step solution

According to given diagram, net charge enclosed through the surface (S₂ ) is zero. Hence, according to Gauss's law, Net flux through surface, ( aligned S₂ & = Charge inclosed ₀ & = 0 ₀ =0 aligned )
