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. when the paper is turned 25 degree with respect to the field the flux through it is:

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

i think the answer would be b

cant without the picture! ?
