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

Answer:

The correct answer to the following question will be Option E (Leaning back the camera such that the plane seems to be in the yz-axis now.).

Explanation:

The given field is:

⇒ [tex]E=EO \ j[/tex]

The above-given field does have an E-field perpendicular to something like the plane.

So,

⇒ [tex]ECos\theta=ECos 90^{\circ}[/tex]

We know that the value of "Cos 90°" is zero.

⇒ [tex]Cos 90^{\circ}=0[/tex]

The other given choices are not related to the given circumstances. So that Option E seems to be the right answer.
