Does the torque exerted on a dipole in a non uniform field depend on the orientation of the dipole with respect to the field justify your answer?

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.

What happens when a dipole is placed in a non uniform electric field?

If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.

What happens if the field is non uniform?

➡️Torque is non zero when dipole is placed in uniform as well as non uniform electric field but in non-uniform electric field, dipole will experience net force of attraction whereas in uniform magnetic field, it doesn’t.

When placed in a uniform field a dipole experiences a a net force B a torque C both a net force and torque D neither a net force nor a torque?

Now, In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction. Though the net force will always be zero, the torque will be in the same direction for both the charges. Hence torque will not be zero.

What is the torque acting on a dipole whose axis is along the electric field?

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.

What happen if field is non uniform?

When an electric dipole is placed in a non uniform electric field experience 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.

What the torque tends to do in case any dipole is kept 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.

What is the torque of a dipole in a non uniform field?

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. Figure given above describes the situation when dipole is placed in a non uniform electric field.

What is an electric dipole moment?

Electric dipole: A pair of electric charges with an equal magnitude but opposite charges separated by a distance d is known as an electric dipole. The electric dipole moment for this is defined as the product of the magnitude of these charges and the distance between them.

What happens if dipole is parallel to the direction of increasing field?

If dipole is parallel to the direction of increasing field, as shown in figure there is a net force on electric dipole along the direction of increasing field. In same way if dipole is antiparallel, there is a net force on dipole in the direction opposite to the direction of increasing field.

What is the net force when electric field is not uniform?

When electric field is not uniform, the net force will be non-zero, there will also be torque on the system. When dipole moment p is parallel or anti-parallel to external field E, the net torque is zero, but there is a force on the dipole E which is not uniform.
