A uniform electric field E = E0 j is set-up in a region of space. A frame is placed in that region in such a way that its plane is perpendicular to the y-axis. Which of the following changes would decrease the magnitude of the electric flux through the frame?A) sliding the frame sideways parallel to the x-axis within the xz-planeB) Sliding the frame sideways parallel to the z-axis within the xz-planeC) moving the frame vertically along the y-axis keeping parallel to the xz-planeD) rotating the frame in the xz-plane with respect to the y-axisE) tilting the frame so that its plane is now in the yz-plane
