The total flux across a Gaussian sphere enclosing an electric dipole is zero. This is because the electric field lines originating from the positive charge of the dipole cancel out the electric field lines terminating at the negative charge within the sphere, resulting in a net flux of zero according to Gauss's Law.

What is the angle between dipole moment and electric field in a electric dipole?

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.


What electric field parallel or anti parallel to the electric dipole?

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.


Why the direction of dipole moment of electric dipole is taken from negative to positive charge?

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.


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?

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.


What is two opposite electric charges separated by a short distance called?

Two opposite electric charges separated by a short distance are called an electric 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.


How does a torque affect the dipole in an electric field?

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.


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 angle between the electric dipole moment and the electric field strength due to it on axial line?

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.


What is difference between between electric dipole moment and magnetic dipole moment?

An electric dipole moment is a measure of the separation of positive and negative charges in a system, creating an electric field. A magnetic dipole moment, on the other hand, is a measure of the strength and orientation of a magnetic field created by a current loop or a moving charge. In essence, electric dipole moments deal with electric fields generated by charges, while magnetic dipole moments pertain to magnetic fields generated by moving charges.


Why is electric field intensity zero at the centre of an electric dipole?

At the center of an electric dipole, the electric field vectors from the positive and negative charges cancel each other out due to their opposite directions. This results in a net electric field intensity of zero at the center of the dipole.
