A square surface of side $L$ meter in the plane of the paper is placed in a uniform electric field $E(volt/m)$ acting along the same plane at an angle $\theta$ with the horizontal side of the square as shown in figure.The electric flux linked to the surface, in units of $volt \;m $

$EL^2$

$EL^2\, cos$ $\theta $

$EL^2\, sin$$\theta $

zero

(AIPMT-2010)

Solution

The flux of electric field $E$ through any area $A$ is defined as – $\phi = E.A cos\theta$ or

$E.A= 0$ the lines are parallel to the surface.

For an electric flux, area must be present for electric lines to pass through it. Whereas in the figure the electric field lines and square both are parallel to each other so there is no flux is present, hence the electric flux is zero.
