A charge q is placed at the corner of a cube of side a . The electric flux through the cube is

Options

  1. Aq ₀
  2. Bq 3 ₀
  3. Cq 6 ₀
  4. Dq 8 ₀

Correct answer

D. q 8 ₀

Step-by-step solution

According to Gauss's law, the electric flux through a closed surface is equal to 1 ₀ times the net charge enclosed by the surface. Since, q is the charge enclosed by the surface, then the electric flux = q ₀ . If charge q is placed at a corner of cube, it will be divided into 8 such cubes. Therefore, electric flux through the cube is ^ = 1 8 ( q ₀ )
