When an electric dipole is placed in an electric field of a point charge then?

If an electric dipole is placed in the field of a point charge, such that the dipole axis (the line joining the two charges) is along a line of force, that is along any radial line with the charge at the origin, the torque on the dipole would be zero, but the force would be non zero.

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

If a permanent dipole is placed in an external electric field, it results in a torque that aligns it with the external field. If a nonpolar atom (or molecule) is placed in an external field, it gains an induced dipole that is aligned with the external field.

What will be the net force acting on an electric dipole placed in a external electric field?

The net force acting on a dipole placed in a uniform electric field is zero. The forces on the two charges constituting the dipole are equal and opposite. Hence, the net force is zero.

What is the torque acting on an electric dipole when placed in an electric field?

0
Hence, the torque acting on the dipole is 0.

What happens when an electric dipole 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.

When an electron and a proton are placed in an electric field?

According to our question, when an electron and a proton are placed in an electric field, due to their opposite polarity they attract each other with an electrical force that is equal in magnitude. But the direction of the force will be opposite due to their opposite charge.

What does happen to an electric dipole when it is placed in a uniform electric field with an angle theta?

An electric dipole in a uniform electric field experiences (When it is placed at an angle theta with the field) In uniform electric field dipole experience only torque, but no force.

What is the net force on an electric dipole?

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.

What is the net force on an electric dipole when it is placed at an angle 30 in a uniform electric field?

Answer: the net force on the dipole is zero but there is a torque.

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

Answer: If the dipole moment vector is not parallel to the direction of electric field then both the charges comprising the dipole experience a force of equal magnitude but in the opposite direction. Thus it experiences only torque.

When the dipole is in stable equilibrium the magnitude of torque is?

zero
Note: Stable equilibrium means the lowest potential energy at the equilibrium point. Therefore the stable equilibrium the torque should be zero and the potential energy of the dipole should be minimum.

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

An electric dipole is placed in an electric field generated by a point charge. Choose the correct option: . For the diplole the electric field acting on the two charges never be equal. Hence the net electric field on the dipole cannot be zero. Thus electric force acting on the the two charges will never cancel each other.

Can the net electric field on a dipole be zero?

 Hence the net electric field on the dipole cannot be zero.  Thus electric force acting on the the two charges will never cancel each other.

When is the torque on a dipole maximum and minimum?

When the dipole is held perpendicular to the field, the torque is maximum. When is the torque on a dipole minimum? When the dipole is parallel to the field, the torque on a dipole is minimum. Give an example of the electric dipole.

What is the net force of a dipole moment?

The forces on the two charges constituting the dipole are equal and opposite. Hence, the net force is zero. What is the SI unit of the dipole moment? The SI unit of dipole moment is Coulomb.meter
