Determine the flux through the top face and the left face of a cube of side 0.01m? The electric field where cube is placed is 10N/C.

Electric flux is a concept used in the field of
electromagnetism. Every electric field creates an electric flux that is proportional to
the electric field lines that go through a given
area.

Electric flux over an area S is equal to the integral
of E*dA over the entire surface area. Electric flux is expressed in the units
N*m^2/C

Here, the electric field is 10 N/C. As the electric
field is constant we can calculate the electric flux through the top face and the left
face by multiplying the electric field by the area of two
faces.

The electric flux through the top face is 10*0.01^2
= 10^-3 Nm^2/C

Similarly, the electric flux through the
left face is also 10^-3 Nm^2/C
