A uniform electric field of magnitude 2500N/C makes an angle of 27 degrees with a plane surface of area 0.355 m2. What is the electric flux through this surface? If this surface is part of a closed box and the flux through remainder of the box is an additional 322 Nm2/C what is the net charge inside the box?
