Electric dipole , electric field at a point on axial and equatorial line due to a dipole
In this assignment we will discuss about Electric dipole , electric field at a point on axial and equatorial line due to a dipole and dipole moment.
Before to read about electric dipole students must have to know about electric field .
Electric dipole – An electric dipole consist of a pair of equal and opposite point charges separated by small distance .
Let two charges of equal magnitude but opposite sign( q and -q) are separated by distance 2a , then the arrangement is known as electric dipole .
Dipole moment (p) – Dipole moment of an electric dipole is the measurement of the strength of the electric dipole its magnitude is the product of magnitude of either charge and separation between them .
i.e. Magnetic moment p = q ( 2a )
Direction of magnetic field is given as negative to positive charge i.e. -q to +q ;
Its SI unit is C-m ( coulomb meter ) and dimension is [M0 L1 T1 A1 ] :
** Dipole field – It is the space around the dipole in which electric effect of the dipole can be experienced . For electric dipole electric field E α 1/r3 but for a point charge E α 1/r2
