Electrostatics question

2010 · Q185

NEETPhysicsElectrostaticsMCQ+4 / −1
A square surface of side L meter in the plane of the paper is placed in a uniform electric field EEE(volt/m) acting along the same plane at an angle θ\thetaθ with the horizontal side of the square as shown in figurre.

AIPMT 2010 Prelims Physics - Electrostatics Question 50 English
The electric flux linked to the surface, in units of volt m is
  1. A
    EL2
  2. B
    EL2cosθ\thetaθ
  3. C
    EL2sinθ\thetaθ 
  4. D
    zero
View written solutionFree
Correct answer: D
Electric flux, ϕ\phi ϕ = EA cos θ\theta θ , where θ\theta θ = angle between E and normal to the surface.



Here, θ=π2\theta = {\pi \over 2}θ=2π​


⇒ϕ\Rightarrow \phi⇒ϕ = 0
