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?

→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?
