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.
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.
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
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.
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 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

That would have to be when the dipole axis is perpendicular to the field.
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)

Applications of electric dipole materials in the field of electronics?
uses of dipole materials
What is the angle between the electric dipole moment and the electric field strength due to it on axial line?
direction-along the axis of dipole from -q to +q.
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.
