zero dipole moment

The measurement of dipole moment helps in distinguishing between polar and non-polar molecules. Non-polar molecules have zero dipole moment while polar molecules have some value of dipole moment. For example: Non-polar molecules: O..

Molecules having two equal and opposite charges separated by certain distance are said to possess an electric dipole. In the case of such polar molecules, the centre of negative charge does not coincide with the centre of positive charge. The extent of polarity in such covalent molecules ..

The Bohr's atom model pictures the electrons to revolve around stationary heavy nucleus of change +ze. The moving electron constitutes a current where e is the electronic charge and T the time period of revolution. Also where v is its orbital velocity and the radius of the orbit. The small mag..

Principle of Moments - If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the anticlockwise h..

Electric field produced by a dipole is known as dipole field. Let +q and -q be equal and opposite point charges separated by a small distance 2l. The strength of an electric dipole is measured by a vector quantity known as electric dipole moment kn..

The potential at point P is the algebraic sum of the potentials due to -q and +q charges. Hence Potential at point P due to the dipole along the equatorial line will be zero as P is equidistant from the two charge..

= 0 (the distance from the line of action to the point O being zero) Resultant moment = 400 N m - 240 N m = 160 N m in the anticlockwise direction. Thus the resultant moment will cause the lamina to turn about O in the anticlockwise directio..

Anti-ferromagnetic substances are expected to possess paramagnetism or ferromagnetism on the basis of unpaired electrons present in them but actually they possess zero net magnetic moment. This is because of the alignment of dipoles is in a compensatory way so as to g..
