Does an electric dipole always experience a torque in electric field when is the torque on the electric dipole maximum and minimum in uniform electric field?

Does an electric dipole always experience a torque in electric field when is the torque on the electric dipole maximum and minimum in uniform electric field?

Case 1: When Ɵ is 900 then Torque is maximum and is equal to pE which means the dipole moment should be perpendicular to the direction of the uniform electric field E. Case 2: When Ɵ is 00, then Torque is minimum.

What will happens when a dipole is placed in an electric field?

When an electric dipole is placed in a uniform electric field, it experiences a torque but no force. In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction. The net force acting on a dipole placed in a uniform electric field is zero.

Do electric fields exert torque on dipoles?

Dipole in an electric field Forces act at different points, therefore they have a nontrivial torque.

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

How does a torque affect the dipole in an electric field? The torque tends to align the dipole in the direction of the electric field. The electrostatic force on a small sphere of charge 0.4 μC due to another small sphere of charge –0.8 μc in air is 0.2 N.

How must an electric dipole be placed in a uniform electric field so that it experiences maximum torque show diagrammatically What is the magnitude of this torque?

i) When torque acting is maximum, dipole should be placed perpendicular to the electric field. ii) When torque acting is zero, dipole is placed parallel to the magnetic field.

When the torque experienced by an electric dipole is maximum and minimum?

When an electric dipole moment is kept in an electric field, force acts on both charges in a dipole. The force acting on the charges acts as a couple and the dipole experiences a torque. The torque is maximum when it makes \[{{90}^{o}}\] with the electric field, which is the most unstable position.

When an electric dipole does placed in a non uniform electric field experiences a zero torque but non zero force?

If the dipole moment p is parallel or antiparallel to the external field E, the net torque is zero but there is a non-uniform force on the dipole E.

How does torque on the dipole in uniform field depends on its orientation?

Electric dipole will experience a torque when dipole vector is not parallel to electric field direction. The torque τ = p × E = pESinθ. when p and E are parallel then angle θ between the two vectors is zero, hence there will not be any torque.

When an electric dipole is placed in an external electric field the dipole?

The external electric field will produce electric force of magnitude qE on positive charge in upward direction and on negative charge in downward direction. We can see that the dipole is in transitional equilibrium as net force on the dipole is zero.

What is the torque acting on an electric dipole placed in a uniform electric field maximum?

Torque is maximum when dipole is held perpendicular to the field.

What is the torque on the dipole?

An electric dipole in an electric field that is external is subjected to a torque written as τ = pE sin θ where symbol θ is the angle which is between p and E. The torque tends to align the moment of the dipole p in the direction of E.

What is torque in electric field?

Torque = Force × distance between forces τ = (q E sinθ) d = q d E sinθ Since ‘qd’ is the magnitude of dipole moment (p), and the direction of dipole moment is from positive to negative charge; torque is the cross product of dipole moment and electric field.
