→If net charge inside a closed surface is negative and a large positive charge is placed outside, what will be the sign of total flux?
Class 12 · Physics
→A Gaussian surface contains a positive charge inside and an equal magnitude negative charge outside. What is the total flux?
Class 12 · Physics
→A Gaussian surface contains a positive charge. If an equal magnitude negative charge is added inside the same surface, what happens to total flux?
Class 12 · Physics
→If net charge inside a closed surface was initially zero and then a positive charge is added inside, what change occurs in total flux?
Class 12 · Physics
→A closed surface contains net positive charge. Can the surface shape be changed so that total flux becomes zero?
Class 12 · Physics
→A closed surface has zero net charge inside, but field is said to be outward everywhere on the surface. Why is this doubtful?
Class 12 · Physics
→If a point charge is off-centre inside a spherical Gaussian surface, why does the simple field calculation fail though total flux is unchanged?
Class 12 · Physics
→A cubical Gaussian surface is chosen for a point charge. Total flux can be obtained by Gauss's law, but why is finding field not as simple as with a sphere?

→If total flux through a closed surface is zero but a dipole is inside, which statement is correct?
Class 12 · Physics
→A closed Gaussian surface is drawn just inside the material of a conductor. If it encloses no net charge, which fact does this match?
