    Answer:

    ФE = 9.403W

    Explanation:

    In order to calculate the magnitude of the electric flux trough the sheet, you use the following formula:

    \Phi_E=\vec{A}\cdot \vec{E}=AEcos\theta       (1)

    A: area of the rectangular sheet = (0.400m)(0.600m) = 0.24m^2

    E: magnitude of the electric field = 95.0N/C

    θ: angle between the direction of the electric field and the normal to the surface of the sheet

    You replace the values of the parameters in the equation (1):

    \Phi_E=(0.24m^2)(95.0N/m)cos(20\°)=9.304W

    The magnitude of the electric flux is trough the sheet is 9.403W
