Question

The Gaussian surface for calculating the electric field due to a charge distribution is :

• A. Any closed surface around the charge distribution.
• B. A cylindrical surface.
• C. A spherical surface.
• D. A closed surface at every point of which electric field has a normal component which is zero or a fixed value.

Answer 1

The correct option is D A closed surface at every point of which electric field has a normal component which is zero or a fixed value.

We must take a surface such that we can able to find the electric field component perpendicular to the surface so that we can calculate the flux associated with the surface.

Therefore, option $\left(d\right)$ is the correct answer.
