Questions & Step-by-Step Solutions

What is the electric flux through a closed surface surrounding a charge Q?
  • Step 1: Understand what electric flux is. Electric flux is a measure of the electric field passing through a surface.
  • Step 2: Know that Gauss's law relates electric flux to the charge enclosed by a surface.
  • Step 3: Identify the charge Q that is enclosed by the closed surface.
  • Step 4: Recognize that ε₀ (epsilon naught) is a constant called the permittivity of free space.
  • Step 5: Use the formula from Gauss's law: Φ = Q/ε₀, where Φ is the electric flux.
  • Step 6: Conclude that the electric flux through the closed surface surrounding the charge Q is equal to Q divided by ε₀.
