An electrical dipole is a couple of two electrical charges identical in amplitude but opposite in sign, say +q and -q (q>0), separated by a distance d.

The angle between the dipole moment and the electric field in an electric dipole is 0 degrees or 180 degrees. This means the dipole moment is either aligned with or opposite to the electric field direction.
An electric field parallel to an electric dipole will exert a torque on the dipole, causing it to align with the field. An electric field anti-parallel to an electric dipole will also exert a torque on the dipole, causing it to rotate and align with the field in the opposite direction.
The direction of the dipole moment of an electric dipole from negative to positive charge is chosen as a convention to align with the direction of the electric field produced by the dipole. This convention allows for easy calculation and understanding of how the dipole interacts with external electric fields.
yes, there is a NET field .electric dipole experiences a net field .(not in uniform E.Field)
The torque on an electric dipole in an electric field is maximum when the dipole is aligned parallel or anti-parallel to the electric field lines. This occurs because the torque is given by the cross product of the electric dipole moment vector and the electric field vector, and it is maximum when the angle between them is 90 degrees.
The electric dipole operator in quantum mechanics is significant because it helps describe the interaction between electric fields and charged particles. It plays a key role in understanding the behavior of atoms and molecules in the presence of electric fields, and is essential for studying phenomena such as molecular bonding and spectroscopy.
Two opposite electric charges separated by a short distance are called an electric dipole.
So interesting query! As we keep the dipole with its dipole moment along the direction of the electric field then it will be in stable equilibrium. IF we keep the same dipole inverted ie its dipole moment opposite to the external field then the dipole will be in unstable equilibrium.
The work done by you to turn the electric dipole end for end in a uniform electric field depends on the initial orientation of the dipole with respect to the field. If the dipole is initially oriented such that its positive and negative charges are parallel to the electric field, then no net work is done as the electric field does not do any work on the dipole as the electric field lines do not transfer any energy. On the other hand, if the dipole is initially oriented such that its positive and negative charges are perpendicular to the electric field, then work is done by you to turn the dipole as the electric field exerts a force on the charges in the dipole in opposite directions, causing them to move in opposite directions. As a result, you have to do work to move the charges and turn the dipole.
A torque applied to a dipole in an electric field causes the dipole to align itself with the direction of the field. The torque will tend to rotate the dipole until it reaches the stable equilibrium position where it is aligned with the electric field.
The angle between the electric dipole moment and the electric field strength on the axial line is 0 degrees (or parallel). This is because on the axial line, the electric field points in the same direction as the electric dipole moment, resulting in the minimum potential energy configuration for the dipole.
