Answer:
The value is [tex]\phi = 70 N\dot m^2 / C[/tex]
Explanation:
From the question we are told that
The area vector is [tex]\vec A = (10i + 8j) \ m^2[/tex]
The electric field is [tex]E = 7 i \ N/C[/tex]
Generally the flux is mathematically represented as
[tex]\phi = \vec E * \vec A[/tex]
=> [tex]\phi = 7i * ( 10 \ i + 8 \ j )[/tex]
=> [tex]\phi = (7 * 10 )\ i[/tex]
Note [tex]i \cdot j = 0[/tex]
=> [tex]\phi = 70 N\dot m^2 / C[/tex]
