Q1:How to calculate electric potential due to a dipole? Q2:How to calculate electric potential due to ring of charges? Q3:How to calculate electric potential due to charge disk? Q4:how to calculate electric potential due to a quadrupole?
A dipole consists of pair of equal and opposite charges i.e., +q and -q, so total charge on an electric dipole is (q)+(-q) = zero.
A dipole moment is defined as the mathematical product of the separation of the ends of a dipole and the magnitude of the charges. Dipole moments are created by the separation of charge over a molecule. Some common molecules with dipoles are H2O, HF, NH3, etc...
Zero Dipole would set itself such that dipole moment vector is along the electric field vector
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.
The correct spelling is dipole moment instead of dipole movement. The definition of dipole moment is the net molecular polarity measure. It is the separation of dipole ends and the magnitude of charges.
Since there is charge separation in a polar covalent bond, there is also resultant electric field from partial positive charge to partial negative charge.hence due to electric field in one direction and also magnitude of equal and opposite charge.....it is a vector.
Hydrogen has a positive charge.
The total electric charge is always zero.

Calculate the field due to an electric dipole of length 10 cm and consisting of charges of -+ 100 μC at appoint 20cm from each charge
The correct spelling is dipole moment instead of dipole movement. The definition of dipole moment is the net molecular polarity measure. It is the separation of dipole ends and the magnitude of charges.
yes, there is a NET field .electric dipole experiences a net field .(not in uniform E.Field)
That would have to be when the dipole axis is perpendicular to the field.
Yes. Total electric charge is always conserved. No exceptions are known.
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.
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.
