What is total charge of electric dipole and force in keeping in uniform 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 net force and torque on an electric dipole in a uniform electric field?

Answer: 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 same direction for both the charges. Hence torque will not be zero.

What is the total force acting on a dipole?

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.

Are deflected in electric field?

Only charged particles can interact with electric fields. X-rays are electromagnetic waves and are not charged. … Alpha particles are basically helium nuclei and are charged. So they are deflected in the electric field.

NEED TO KNOW:  Why is drift velocity opposite to electric field?

What is the net force on a dipole in an 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.

Which of the following is uniform electric field?

Answer: c) Two parallel plates.

Where is the electric field the most uniform How can you tell?

Field-Line Patterns

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest. If the lines are uniformly-spaced and parallel, the field is uniform.

Is the force constant in a uniform electric field?

A uniform electric field consists of two conducting plates. These plates are oppositely charged, and infinitely wide. … This force remains constant as the charge travels within the electric field.

What happens when a dipole is placed in 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 is an electric dipole give two examples?

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.

NEED TO KNOW:  You asked: How much electricity can a dynamo generate?

How do you calculate electric dipole moment?

The formula for electric dipole moment for a pair of equal & opposite charges is p = qd, the magnitude of the charges multiplied by the distance between the two.
