Question
A square surface of side $$L$$ metre in the plane of the paper is placed in a uniform electric field $$E\left( {\frac{V}{m}} \right)$$ acting along the same place at an angle $$\theta $$ with the horizontal side of the square as shown in figure. The electric flux linked to the surface in unit of $$V$$ - $$m,$$ is
A square surface of side $$L$$ metre in the plane of the paper is placed in a uniform electric field $$E\left( {\frac{V}{m}} \right)$$ acting along the same place at an angle $$\theta $$ with the horizontal side of the square as shown in figure. The electric flux linked to the surface in unit of $$V$$ - $$m,$$ is
A.
$$E{L^2}$$
B.
$$E{L^2}\cos \theta $$
C.
$$E{L^2}\sin \theta $$
D.
$$0$$
Answer :
$$0$$
Solution :
Flux of electric field $$E$$ through any area $$A$$ is defined as $$\phi = E \cdot A\cos \theta $$ or $$\phi = E \cdot A = 0,$$ the lines are parallel to the surface.
