Question

what is electric dipole.? why do we assume the electric dipole to be small in size in most of the cases.??​

Answer 1

Answer:

A system of two equal and opposite charges placed at some separation is called electric dipole.

The concept of electric dipole is useful at a molecular level and that is why we refer small dipole as an ideal dipole.

In some molecules the centre of positive charge get shifted from the centre of negative charge. such a molecule behaves like one electric dipole.

Answer 2

Answer:

An electric dipole is two charged objects,

with equal but opposite electric charges, that are

separated by a distance. The electric field caused

by a dipole falls off as the cube (third power) of

the distance from the dipole, and has a directional

variation that depends on whether you’re moving

along the line separating the two charges or

perpendicular to it. A dipole can be created, for

example, when you place a neutral atom in an

electric field, because the positively-charged

constituents of the atom will be pulled one way,

and the negatively-charged constituents the other

way, creating a separation of charge in the

direction of the field.
