## Homework Statement

The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface (1) has an area of 2.20 m², while surface (2) has an area of 3.90 m². The electric field in the drawing is uniform and has a magnitude of 200 N/C. Find the magnitude of the electric flux through surface (2) if the angle θ made between the electric field with surface (2) is 35.0°.

## Homework Equations

I used gausse law

## The Attempt at a Solution

(200)(2.20)cos(35)=360.4

(200)(3.90)cos(35)=638.9

Sinnce they are looking for magnitude of surface 2 I thought the answer was 638.9 but I got it wrong.[/B]
