question 139

Multiple Choice

An constant electric field, $$\overrightarrow { \mathbf { E } } = ( 3 \tilde { \mathbf { i } } + 4 \hat { \mathbf { j } } )$$ N/C,goes through a surface with area $$\overrightarrow { \mathbf { A } } = ( 8 \hat { \mathbf { i } } - 6 \hat { \mathbf { k } } )$$ m².(This surface can also be expressed as an area of 10 m² with the direction of the unit vector ( $0.8 \tilde { \mathbf { i } } - 0.6 \tilde { \mathbf { k } }$ ) .What is the magnitude of the electric flux through this area?

• A)24 N . m²/C
• B)48 N . m²/C
• C)0.24 N . m²/C
• D)0.48 N . m²/C
• E)0
