Answer #1

Solution:

flux at top is more than the flux at bottom , flux at top is positive and flux at bottom is negative, Hence the resultant flux is positive.

So we can say that the charge must be positive.

thanks.

    Electric charge produces an electric field, and the flux of that field passing through any closed surface is proportional to the total charge contained within that surface. In other words, if you have a real or imaginary closed surface of any size and shape and there is no charge inside the surface, the electric flux through the surface must be zero. (i) In your own understanding kindly represent the above statement to its mathematical formula.
