A large plane charge sheet having surface charge density σ=2.0×10−6 Cm−2 lies in the x-y plane. Find the flux of the electric field through a circular area of radius 1 cm lying completely in the region where x, y, z are all positive and with its normal making an angle of 60∘ with the z-axis. (Given that the field due to infinite charged sheet is σ2ϵ0 where σ = surface charge density. Also note that it is perpendicular to the sheet and is constant for all points from the sheet.)
Electric field intensity at a point due to an infinite sheet of charge having surface charge density σ is E. If the sheet were conducting, electric intensity would be
