CBSE Class 12-science Answered
A point charge is placed at the centre of a closed Gaussian spherical
surface of radius r. Electric flux passing through the surface is Φ. How is
the electric flux Φ through the surface affected when the following
changes are made in turn:
(i) The spherical surface is replaced by a cylindrical surface of the
(ii) The point charge is replaced by an electric dipole? Justify your
answer in each case.
