Explain Dipole???
Its Shivika Tiwari......
Answers
An electric dipole is two charged objects, with equal but opposite electric charges (say a +q and a -q), that are separated by a small distance.
The electric field caused by such a dipole falls off as ( 1/r^3) of the distance(r) from the centre of dipole,
and It has a directional variation (r, theta).
A dipole can be created, e.g. , suppose 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.
Materials placed in a field of Force may deform and such molecules /atoms are called Polar.
A charge distribution placed in a region may lead to multipolar fields in the space and dipole happens to be the simplest.
There can be quadrupolar field or higher order terms in a multipole expansion in general.
Hope this helps you Shivika.
Answer:
A dipole is a separation of opposite electrical charges. A dipole is quantified by its dipole moment (μ). A dipole moment is the distance between charges multiplied by the charge. ... The direction of an electric dipole moment points from the negative charge toward the positive charge.
