    22.66Nm²/C

    Explanation:

    Flux through an electric field is expressed as ϕ = EAcosθ

    When a piece of paper is held with one face perpendicular to a uniform electric field the flux through it is 25N. m^2/c. If the paper is turned 25 degree with respect to the field the flux through it can be calculated using the formula.

    From the formula above where:

    EA = 25N. m^2/C

    θ = 25°

    ϕ = 25cos 25°

    ϕ = 22.66Nm²/C
