What is the motion of dipole in uniform electric field?

When an electric dipole is placed in a uniform electric field making an angle with the direction of the field as shown in the figure. Thus, electric dipole is under the action of two equal and unlike parallel forces, which give rise to a torque on the dipole.

When an electric dipole is placed in a nonuniform electric field a force on the dipole is zero?

Its dipole moment is given as a product of charge and the separation between the charges. The direction of electric dipole moment is from negative to positive charge. Hence the resultant force will always be non-zero.

What happens when electric dipole is placed in non uniform electric field what will be the force and torque acting on the dipole?

Force and torque. So, when the electric field is not uniform then the net force will be non-zero and there will also be torque on the following system. 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.

When a dipole is placed in a uniform external field?

Question: An electric dipole is placed at an angle of 30o with an electric field of intensity 2×105 N/C. It experiences a torque of 4Nm. Calculate the charge on the dipole if the dipole length is 2cm.

Will an electric dipole have translational motion when placed in a non uniform electric field give reason?

When a dipole is placed in a non uniform electric field it will experience both net force and torque . Thus , it willexecute both rotatory and translatory motion . This is the physical significance of torque experienced by a dipole in an electric field.

What would happen if dipole is kept in a non uniform electric field which increases its magnitude parallel to dipole moment p?

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

When a dipole is placed in a uniform field Anti parallel with it then it is in?

A dipole placed in a uniform electric filed is in Stable equilibrium when the electric field is directed along the direction of the dipole i.e., when is parallel to. Unstable equilibrium when the electric filed is directed at an angle of 180 degrees with the direction of the dipole, i.e., when is anti-parallel to.

What is dipole in a uniform external field Class 12?

Dipole in a uniform electric field. Dipole in a uniform electric field. When two charges in a dipole are separated by some distance, the forces acting at different points result in torque on the dipole. • The torque tries to align the dipole with electric field.

Can an electric dipole in an uniform electric field have I translator motion II rotator motion?

When an electric dipole is placed in a uniform field at an angle θ with the field, the dipole experiences a torque. In this way, dipole will have both rotational as well as linear motion. So, both assertion and reason are true. Reason also explains the assertion.

What happens if the field is not uniform?

(ii) In case of non-uniform field, force acting on both the ends will not be equal. So, they will act as combination of couple and a net force. In this way, dipole will have both rotational as well as linear motion.

Which orientation a dipole placed in a uniform electric field is in a stable b unstable equilibrium?
