→For a plane surface, the area vector points upward while the electric field points downward. What is the sign of the electric flux?
Class 12 · Physics
→A closed surface encloses the positive charge of a dipole, while the negative charge lies outside it. The surface is then enlarged to enclose both charges. What happens to the net electric flux?
Class 12 · Physics
→A complete electric dipole is inside a closed surface. The net flux is zero, but will the electric field be zero everywhere on the surface?
Class 12 · Physics
→A closed surface is changed from a sphere to an irregular shape while the enclosed net charge remains the same. Why does the total flux not change?
Class 12 · Physics
→A charge inside a closed surface is moved from the centre to a position near the surface. What happens to the total flux?
Class 12 · Physics
→A positive charge is placed at the centre of a cube. By symmetry, what fraction of the total flux passes through each face?
Class 12 · Physics
→Net flux through a closed surface is zero, yet field lines leave one part of the surface and enter another part. How is this possible?
Class 12 · Physics
→A closed surface contains two positive charges and one negative charge whose net charge is positive. A large negative charge is placed outside. What determines the net flux through the closed surface?
