For everyone, in this question, we're given an infinite plane which has a uniform surface charge sigma of 8 piccolum per meter square.
00:09
The uniform surface charge is nothing but the surface charge density.
00:13
So sigma can be written as 8 multiplied by 10 to the power minus 12 coulum per meter square.
00:20
Since the infinite plane has a uniform surface charge, this implies that it will have an electric flux.
00:26
We have to find out the electric flux due to this infinite plane.
00:29
Then in the second part of the question, we have to write the expression of magnitude of the electric field above the infinite brain here.
00:37
And in the last part, we have to calculate the magnitude of electric field at a height h which is given as 8989 meter.
00:43
Now, first of all, we have considered a closed surface which is cylindrical in shape and the cross -sectional area of this closed surface is supposed as delta -s.
00:57
The charge that is enclosed by the closed surface is equal to q enclosed...
