(i) Electric field of a short dipole is maximum along its axial line. vecE("axial") = 1/(4pi epsi0). (2 vecp)/r^3 (ii) Electric field of a short dipole has a least magnitude along its equatorial line. vecE("equatorial")= - (1)/(4pi epsi0). (vec p)/r^3 On the basis of your understanding of the following paragraph and the related studied concepts.

An electric dipole is a pair of equal and opposite point charges q and -9 separated by a distance '2a'. The total charge of the electric dipole is obviously zero but the field of the electric dipole at a point is non-zero because electric fields due to + qand - q charges at the point do not exactly cancel out. Electric field of a dipole, at large distances, depends on the product 'qa'. So we define a term dipole moment vector

→ p

of an electric dipole as

→ p = q ( 2 a )

and its direction is along the line from q to + q charge. The dipole field at large distances fall off as

1 r 3

. Further, the magnitude and direction of the dipole field depends not only on the distance r but also on the angle between the position vector

→ r

and the dipole moment

→ p .

Concept of electric dipoles is very significant for different materials. In most molecules, the centres of positive charges and of negative charges exactly coincide and their dipole moment is zero. However they develop a dipole moment when an electric field as applied. Such molecules are termed non-polar molecules. But in some molecules, the centres of positive charges do not exactly coincide with that of negative charges and the molecules has a permanent dipole moment even in the absence of an electric field. Such molecules are called polar molecules. Various materials give rise to interesting properties and important applications in the presence or absence of electric field.

In which direction is the magnitude of electric field due to a short dipole (i) maximum, (ii) minimum ? Write expression for the same.

Text Solution Solution

(i) Electric field of a short dipole is maximum along its axial line.

→ E axial = 1 4 π ε 0 . 2 → p r 3

(ii) Electric field of a short dipole has a least magnitude along its equatorial line.

→ E equatorial = − 1 4 π ε 0 . → p r 3

Cone duet with the negative on the convex surface and positive on the concave surface of the toroid (electron & positron) facing the high frequency neutral tron or neutron.

There's radiation of energy (light from LED). There's oscillation at the neutron region.

There's drop in potential when energy is radiated, being 3v for blue and 1.8v for red 🔴.

A superconductor doesn't radiate significant energy, so it's characteristic features.

For the dipole electric field is varies as?

A dipole’s electric field varies as 1/r^3.

You can calculate that e.g. by taking two charges: q, -q with distance d between them.

Next:

Figure out the electric field by summing up the field form the individual charges.

See what the field is for r>>d.

You will thus arrive at an expression for a dipole field and notice the 1/r^3 dependence.

How does an external electric field affect a dipole?

An external electric field will affect a dipole by causing its positive and negative charges to be separated, resulting in the creation of an electric dipole moment. This means that the positive charge will be attracted to the negative pole of the electric field, while the negative charge will be attracted to the positive pole of the electric field. As a result, the dipole will experience a force that will tend to align it with the electric field.

For example, consider a simple dipole consisting of a positive charge and a negative charge separated by a small distance. If this dipole is placed i
