From the given diagram it is clear that when the circular loop is rotated about the axis A-B the electric field, area of the circular loop, and the angle between the circular loop and the electric field will remain unchanged. Gausss Law states that the flux of electric field through a closed surface is equal to the charge enclosed divided by a constant.

So initially the angle between the rectangular loop and the electric field is 90°.

From the diagram, it is clear that initially, the plane of the circular loop is parallel to the electric field.

Where θ = angle between the surface and the electric field where E is the electric field vector, d A is a small amount of area, and n is a unit vector perpendicular to the surface d A.

The expression for electric flux is: E E n d A. If the electric field is E and the area is A then the electric flux associated with the area is given as, Electric flux Electric field Area (angle between the planar area and the electric flux) The equation is: E A cos() Where: : Electric Flux. The electric flux is simply the amount of electric field passing through a surface.The SI unit of the electric flux is N-m 2/C.It is defined as the number of electric field lines associated with an area element.

Therefore, total flux through the faces of the given cube = q/2ϵ 0.If the charge q is placed at C, the center of a face of the cube, it is being shared equally by 2 cubes.If A point charge q is placed at a distance x/2 directly above the center of a cube of side x, it will be at the face of the cube.The magnitude of flux ϕ = Q / ϵ 0 (if the charge is placed at the center of the cube).According to this law, the total charge Q enclosed in a closed surface is proportional to the total flux ϕ enclosed by the surface.Gauss' Law: This law gives the relation between the distribution of electric charge and the resulting electric field.Where ϕ is the flux, E is the electric field, and dA is the small area. The electric flux through a chosen surface is given by: Electric flux (ϕ): The number of electric field lines passing through a surface area normally is called electric flux.
