When dipole is parallel to electric field the force experienced by it is?

In particular, note that the torque is zero when the dipole and electric field vectors are parallel. Thus, a dipole will always experience a torque that tends to align it with the electric field vector. The dipole is thus in a stable equilibrium when it is parallel to the electric field.

When electric dipole is aligns parallel to the field then torque on a dipole becomes?

In case the electric dipole gets parallel or antiparallel to the electric field then the torque will be zero. So, the correct answer is “Option B”.

What is the net force experienced by the 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 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 will be the electric force acting on an electric dipole placed in a uniform electric field?

Hence, the electric force on a dipole when it is placed in a uniform electric field is always zero.

What happens when a dipole is placed in a non uniform electric field parallel to the 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.

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.

Why dipole experiences torque in the 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.

When an electric dipole is placed in a uniform electric field with its dipole moment parallel to the field it will experience?

Electric dipole in a uniform electric field

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.

Why is net force on the dipole zero?

When a dipole is immersed in a uniform electric field, as illustrated in Figure 16.4. 3, the net force on the dipole is zero because the force on the positive charge will always be equal and in the opposite direction from the force on the negative charge.

What is the net force in an electric field?

The attractive or repulsive interaction between any two charged objects is an electric force. … The magnitudes of the forces are then added as vectors in order to determine the resultant sum, also known as the net force. The net force can then be used to determine the acceleration of the object.

When an electron and 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 is an electric dipole in stable equilibrium in an electric field?

A dipole in stable equilibrium, when Electric filed and dipole moment are perpendicular to each other i.e. the angle between them is zero degrees and torque will be maximum.

When electric dipole is placed in a uniform electric field its two charges experience equal and opposite forces?

When electric dipole is placed in uniform electric field, its two charges experience equal and opposite forces, which cancel each other and hence net force on electric dipole in uniform electric field is zero.
