Question

the electric flux through any closed spherical surface enclosing a charge q is​

Answer 1

For calculating electric flux due to enclosed charge, gauss theorem is used.

ϕ = E.ds = q/ϵo

ϕ = E.4πrl² = λl/ϵo

ϕ = 1/4πϵo * 4πl² = λ/ϵo

ϕ = λl/q

Answer 2

The electric flux through any closed spherical surface enclosing a charge q is - Ф = q /∈₀.

• Electric flux is the product of electric field intensity and the area of the surface.
• It can also be defined as the ratio of the charge enclosed by a body to the permittivity in the free space.
• The mathematical expression for the electric flux is:

        Ф = q /∈₀

        here, Ф is the electric flux

        q is the charge enclosed by the spherical surface

        ∈₀ is the permittivity of the free space

• The above equation depicts that electric flux through a body is 1/∈₀ times the charge enclosed by it.
