MCQ
A rectangular surface of sides $10 \,cm$ and $15 \,cm$ is placed inside acyniform electric field of $25 \,V / m$, such that the surface makes an angle of $30^{\circ}$ with the direction of electric field. Find the flux of the electric field through the rectangular surface .................. $Nm ^2 / C$
  • A
    $0.1675$
  • $0.1875$
  • C
    $0$
  • D
    $0.1075$

Answer

Correct option: B.
$0.1875$
b
(b)

$\phi=E A \cos 30^{\circ}$

$=0.1875 \,Nm ^2 / C$
