Questions & Step-by-Step Solutions

In a region where the electric field is uniform, what is the shape of the Gaussian surface that would yield the simplest calculation of electric flux?
  • Step 1: Understand what a Gaussian surface is. It is an imaginary closed surface used to apply Gauss's law.
  • Step 2: Know that electric flux is calculated through this surface based on the electric field.
  • Step 3: Recognize that in a uniform electric field, the field strength is the same everywhere.
  • Step 4: Identify that a flat plane (or a rectangle) is the simplest shape to use as a Gaussian surface in a uniform electric field.
  • Step 5: Understand that using a plane makes it easy to calculate the area and the angle between the electric field and the surface.
  • Step 6: Conclude that a plane allows for straightforward calculations of electric flux because the electric field is constant across the surface.
