An electric field is constant at every point on a square surface that is 0.80 m on a side. this field has a magnitude of 3.5 n/c and is oriented at an angle of 35° with respect to the surface, as the drawing shows. calculate the electric flux φe passing through the surface.

Explanation:

As we know that electric flux is defined as

now we have

also we know that electric field makes and angle of 35 degree with surface

so angle made by electric field with Area vector is given as

there are no contact forces mentioned on the list of choices that you've provided.
