If an electric field is given by . Calculate the electric flux through a surface of area 10 units lying in YZ plane

Area of the given surface in YZ plane = 10 units

The direction of the area vector is specified by the normal to the plane. This is shown below:

Area = 10 units

And,

Here, the plane is YZ, so area vector cannot be in x-direction.

So,

Or,

Electric Flux: Electric Flux through a given area held inside an electric field is the measure of a total number of electric lines of force normally passing through that area.

Flux =

= 100 units
