Q. A rectangular surface of sides $10 c m$ and $15 c m$ is placed inside a uniform electric field of $25 V / m$ , such that the surface makes an angle of $3 0^{\circ}$ with the direction of electric field. Find the flux of the electric field through the rectangular surface

$0.1675 N / m^{2} C$

$0.1875 N m^{2} / C$

Zero

$0.1075 N m^{2} / C$

$ϕ = E A cos 3 0^{\circ}$
$= 0.1875 N m^{2} / C$
