An infinite, uniformly charged sheet with surface charge density `sigma` cuts through a spherical Gaussian surface of radius `R` at a distance `X` from its center, as shown in the figure. The electric flux `Phi` through the Gaussian surface is .

Answer

D

Explanation

`:'` Electric field
`=sigma/in_(0)` due to infinitely uniform charged.
Electric flux
`=(Sigma_("enclosed"))/in_(0)=int sigma/in_(0)xx[piR^(2)-pix^(2)]`
