Electrostatics investigates interaction between fixed electric charges
The Gauss' Law is used to find electric field when the charge is continuously distributed within an object with symmetrical geometry, such as sphere, cylinder, or plane. Gauss' law follows Coulomb's law and the Superposition Principle.
The Gauss’ law of electrostatics is one of the most fundamental theorems in Electrostatics. It states that the Electric flux ϕ through a closed surface is 1ϵ0 times the charge enclosed by that surface.
Suppose if I consider a sphere having a point charge q situated at its centre. The electric field due to the point charge should be directed radially outward. At each and every point on the surface of the sphere, the electric field intensity E and the normal to the surface n^ is in the same direction. So the angle θ between them must be 0°.
