Charges `Q_1 and Q_2` lie inside and outside, respectively, of a closed surface S. Let E be the field at any point on S and `phi` be the flux of E over S.

If charge q1 and q2 lies inside and outside respectively of a closed surface S. Let E be the electric field at any point on S and ϕ be the electric flux over S. Select the incorrect option.

Show that the electric flux through a closed surface S is q//in_0

If the inward and the outward electric flux through a closed surface be phi _(1) and phi _(2) , the charge inside the closed surface is

A conducting sphere S_(1) intersects a closed surface S_(2) as shown in the figure.A positive charge q is placed at a point P .What is the value of electric flux through the surface S_(2) ? q P

Three point charges are placed as shown in the figure. S is a gaussian surface phi is the net flux passing through surface A and E be the electric field at point P on the surface, then

A charge q is inside a closed surface and charge -q is outside. The out going electric flux is

The electric flux through a chlosed surface area S enclosing charge Q is phi . If the surface area is doubled, then the flux is
