Is it necessary for an electric dipole to experience a net force as well as a torque when it is placed in a non uniform electric field?

When a dipole is placed in an electric field, the opposite charges on the dipole both experience a force due to the electric field. Hence the dipole will experience both force and torque when placed in a non uniform electric field. Therefore, the correct answer is option (B).

What condition is required for a dipole to experience a net force from an electric field?

1 An electric dipole experiences a net electric force if the positive charge q is subject to an electric field E (r + d) that differs from E(r) acting on the negative charge q.

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

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.

Is it necessary for an electric dipole to experience a net force?

Definitely Yes for the both. The non-uniform electric field be averaged in effective ares of interaction of the electric field and dipole field. If a dipole placed in non-uniform electric field, it will experience net force of attraction per meter towards electric field of large magnitude that is, F(net)=p(E2-E1).

Does an electric dipole experience a force when placed in the uniform electric field explain?

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.

When an electric dipole is placed in non-uniform electric field it experiences?

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.

When an electric dipole is placed in a uniform electric field it experiences?

When an electric dipole is placed in a uniform electric field, it experiences a torque but no force. An electric dipole placed in a uniform electric field experiences a torque that aligns the dipole parallel to the direction of the electric field with zero net force.

When electric dipole is placed in a non uniform electric field it experiences?

What is the net force experienced by the dipole?

zero
Therefore, the net force on the dipole is zero. Even if we change the orientation, the length and the charge of the dipole, the net force on the dipole will be equal to zero. Hence, the electric force on a dipole when it is placed in a uniform electric field is always zero.

Does an electric dipole always experience a torque in electric field?

When a dipole is placed in a uniform electric field and dipole vector direction is not parallel to field direction, each chargs of dipole experiences a force. Magnitude of the two forces are equal but in opposite direction. Hence in uniform field, dipole experiences only torque.

What is the net force experienced by a dipole in electric field?

In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction. Hence the net force will always be zero. Net force (as well as torque) are experienced by the dipole in a non uniform electric field. Was this answer helpful?

How do you find the torque of an electric dipole?

Since the force magnitudes are equal and are separated by a distance d, the torque on the dipole is given by: Torque (τ) = Force × distance separating forces . The torque on an electric dipole in a uniform electric field is given by the equation \\(\\vec{\au}=\\left |\\vec{\au}\imes \\vec{\\\\E} \\right|=pE\\sin \\Theta\\)

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.

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.
