Gauss's law helps in:

Options

  1. ADetermination of electric force between point charges
  2. BSituation where Coulomb's law fails
  3. CDetermination of electric field due to symmetric charge distributions
  4. DDetermining electric potential due to symmetric charge distributions

Correct answer

C. Determination of electric field due to symmetric charge distributions

Step-by-step solution

The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field. Gauss's Law is a general law applying to any closed surface. It is an important tool since it permits the assessment of the amount of enclosed charge by mapping the field on a surface outside the charge distribution. For geometries of sufficient symmetry, it simplifies the calculation of the electric field.
