Electric flux

  1. Oct 6, 2011 #1
    1. The problem statement, all variables and given/known data

    Determine the electric flux through a 6m by 4m rectangular area. The area is oriented such that a vector normal to its surface points in the [1;6] direction. The electric field is [7;1] N/C.

    2. Relevant equations

    Φ=E·A=EA*cosθ

    3. The attempt at a solution

    [7;1]N/C*[24;144]m2=312 Nm2/C

    I did this is wrong, right? How should i go about solving this, doesn't the electric flux equal the dot product of the electric field and the normal vector multiplied area. Am I missing something here?

    Why do you think you did it wrong? It looks right to me.

    i always second guess myself, it's a problem I missed the day we learned about EF because of a funeral and i've been playing catch up ever since.
