A closed surface is vacumm encloses charges `-q and +3q`. Another charge `-2q` lies outside the surface. Total electric flux over the surface is

A closed surface in vacuum encloses charges -q and +3q . The total electric flux emerging out of the surface is:

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

There is a point charge +q inside a hollow sphere and a point charge -q just outside its surface. The total flux passing through the surface of sphere 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

Figure shows three point charges +2q,-q and +3q. Two charges +2q and -q are enclosed within a surface .S.. What is the electric flux due to this configuration through the surface.S?
