The electric flux through the surface

Options

  1. Ain figure (c) is the largest
  2. Bin figure (b) is same as figure (c) but is smaller than figure (d)
  3. Cis the same for all the figures
  4. Din figure (d) is the least

Correct answer

C. is the same for all the figures

Step-by-step solution

Comparing electric flux through surfaces enclosing charge +q: Gauss's Law states that the electric flux _E through any closed surface depends only on the enclosed charge: _E = Q_ enclosed / ₀ . Since all four surfaces enclose the same charge +q , the flux is identical for each: _a = _b = _c = _d = q / ₀ . The flux is independent of the surface shape or size, rendering options A, B, and D incorrect. The correct choice is C, affirming flux equality across all figures.
