You asked: What is the net force on a dipole placed in a uniform electric field?

What is the net force on a dipole in uniform electric field?

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 placed in the electric field of a point charge?

The net electric force on the dipole must be zero.

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.

Does a perfect electric dipole feel a net force in a uniform electric field?

A perfect electric dipole feels a net force in a uniform electric field. … The net outward electric flux passing through any closed surface is equal to the net charge enclosed by the surface divided by a constant.

When a uniform field is a dipole experience?

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 happen 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 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.

Which of the following is correct the electric field at a point is?

Electric field at a point is continuous if there is no charge at that point. And the field is discontinuous if there is charge at that point. So both options (b) and (c) are correct.

What is the net force acting on a dipole in non uniform electric field?

The resultant force acting on the dipole is always zero.

What is the force on dipole due to charge?

The total force on the dipole is the sum of the forces on the individual charges. Unless the electric field at the location r + d of the positive charge differs from that at the location r of the negative charge, the separate contributions cancel.

What is an electric dipole give two example?

Dipole-dipole forces are the attraction between the positive end of one molecule and the negative end of another. Ammonia molecule (NH 3) is an example of electric dipole.In NH 3, the centre of mass of positive charge and centre of mass of negative charge are some distance apart hence resulting in a dipole.

What is relation between electric field and force?

The strength of electric field at a particular point is called as Electric Field intensity. In other words, the force felt by a unit positive charge situated at a point is called Electric field intensity.

What is the difference between electric field and force?

A force that causes motion in those other interacting objects. A field is a way to explain how forces can be applied without physical touch. A charge is pulling in something else with an electric force without touching it – the “stuff” that connects the charge with its force through empty space is the electric field.

Can electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
