What is the significance of electric dipole in a polar molecule when an external electric field is applied?
in magnetic relays
An electric dipole placed with its axis inclined at an angle to the direction of a uniform electric field experiences?
It experiences a torque but no force. As the dipole is placed at an angle to the direction of a uniform electric field it experiences two opposite and equal forces which are not along the same line. This develops a torque which aligns the dipole along the field. The dipole does not experience any force as the two forces cancel each other.
What kind of charge would an electric dipole have on a hydrogen atom?
Hydrogen has a positive charge.
Why does CO2 have a permanent dipole-dipole interaction?
Carbonate (CO3 2-) is trigonal planar with a central C and three O's 120 degrees from each other (D3h symmetry). All the O's have the same electron density because of resonance. This gives carbonate no dipole.
Why do polar molecules absorb IR?
You can view incident IR radiation as an oscillating electric field ( the 'wave-like' view of EM radiation.) As such, it effects the vibration of a molecule by inducing a dipole oscillation of the same frequency. The connection is most clearly seen if you consider that the induced dipole oscillation produces an identical oscillating electric field to the field that induced it. A molecule can only produce an oscillating electric field by vibration if its vibration produces a change in dipole moment (a non-polar molecule would produce a constant electric field regardless of the vibration.) I hope that helps
What is the angle between dipole moment and electric field in a electric dipole?
Zero Dipole would set itself such that dipole moment vector is along the electric field vector
What is difference between between electric dipole moment and magnetic dipole moment?
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.
An electric dipole is placed in a nonuniform electric filedIs there a net force on the dipole?
yes, there is a NET field .electric dipole experiences a net field .(not in uniform E.Field)
When is the torque on an electric dipole in an electric field is maximum?
That would have to be when the dipole axis is perpendicular to the field.
You turn an electric dipole end for end in a uniform electric field.How does the work you do depend on the initial orientation of the dipole with respect to the field?
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.
Which orientation of an electric dipole in an uniform electric field would correspond to unstable equilibrium?
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.
What is the expression for the electric field in the perpendicular bisector plane of a dipole?
expression for the electric field in the perpendicular bisector plane of a dipole
Applications of electric dipole materials in the field of electronics?
uses of dipole materials
Which orientation of an electric dipole in a uniform electric field would correspond to stable equilibrium?
when angle 0 b/w dipole moment vector p and electric field vector E is zero then potential energy of dipole, U=-pEcos0 =-pE and torque=pEsin0=0;which means that the electric dipole is in stable equilibrium.
What is two opposite electric charges separated by a short distance called?

What is the total charge on an electric dipole?
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?
How electric field is equal to force by dipole moment?
when dipole moment,torque and electric field all the three are perpendicular to each other.
