A charge q is located at the centre of a cube. The electric flux through any face is

Options

  1. A4 q 6 (4 ₀ )
  2. Bq 6 (4 ₀ )
  3. Cq 6 (4 ₀ )
  4. D2 q 6 (4 ₀ )

Correct answer

A. 4 q 6 (4 ₀ )

Step-by-step solution

According to Gauss's theorem, electric flux through the cube (closed surface), = q ₀ Since, cube has six surfaces and all the faces are symmetrical, therefore electric flux through any face ^ = q 6 ₀ = 4 q 6 (4 ₀ )
