Physics & Space Science

A region of space contains a uniform electric field oriented along the y-axis. A frame of surface area A is placed perpendicular to the y-axis in the xz-plane. The magnitude of the electric flux through this frame is ?0

A second frame is placed in the same electric field in such a way that the magnitude of the electric flux through it is ?0/2. How is the plane of second frame oriented with respect to the plane of the first one? A) at a 90° angle B) at a 60° angle C) parallel to the first frame D) perpendicular to the first frame E) at a 30° angle
