→Which statement is correct about field direction and dipole moment direction at a far point on the axial line of a dipole?
Class 12 · Physics
→A dipole is observed to be pulled toward a region of stronger field. This can indicate what kind of field?
Class 12 · Physics
→Net force on a dipole is zero in a uniform electric field. If the field becomes non-uniform, why need the net force not remain zero?
Class 12 · Physics
→Dipole moment is exactly opposite to the electric field. Why does a slight displacement prove the position unstable?
Class 12 · Physics
→The angle between dipole moment and electric field is zero. If the dipole is slightly rotated, in which tendency will torque act?
Class 12 · Physics
→Dipole moment makes 60 degrees with the field. If the angle is changed to 30 degrees while other quantities remain same, how does torque change?
Class 12 · Physics
→In a uniform electric field, net force on a dipole is zero. When will its torque be maximum?
Class 12 · Physics
→A dipole has zero net charge. Still why is its field at a far point small but not necessarily zero?
Class 12 · Physics
→A dipole moment has to be made four times while separation is made half. What should be done to the charge magnitude?
Class 12 · Physics
→The charge of a dipole is made three times and the separation is made one third. What happens to the dipole moment?
Class 12 · Physics
→If net charge inside a closed surface is positive but field is inward through some parts of the surface, what is the sign of total flux?
Class 12 · Physics
→An external positive charge is kept near a closed surface but no charge is inside it. Why will the total closed flux be zero?
Class 12 · Physics
→On a closed surface, flux is positive through some parts and negative through others. What is the correct way to find total flux?
Class 12 · Physics
→If the angle between area vector and electric field is 90 degrees, why will flux remain zero even if the field is very large?
Class 12 · Physics
→A surface is rotated so that the angle between area vector and electric field changes from 60 degrees to 30 degrees. With other factors unchanged, how does the flux change?
Class 12 · Physics
→The area vector of an open plane surface makes 120 degrees with the electric field. What will be the sign of flux?
Class 12 · Physics
→If the shape of a closed surface is changed but the net enclosed charge does not change, why does total electric flux remain unchanged?
Class 12 · Physics
→A complete electric dipole is placed inside a closed surface of any shape. Why will the net electric flux be zero?
Class 12 · Physics
