MCQ on Electric flux
The total number of electric field lines passing a given area in a unit time is defined as the electric flux.
Electric flux
If the plane is normal to the flow of the electric field, the total flux is given as:
Φ=EA
When the same plane is tilted at an angle Ɵ, the projected area is given as AcosƟ and the total flux through this surface is given as
Φ = EACosθ
Where,
E is the magnitude of the electric field
A is the area of the surface through which the electric flux is to be calculated
Ɵ is the angle made by the plane and the axis parallel to the direction of flow of the electric field
