dipole moment d

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 2 , Cl 2 ..

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..

Clockwise moment and anticlockwise moment about 50 cm divisions are equal. Suggested answer : 20 x d = 40 x 20 Therefore, Hence the 20 N force of B is acting from 90 cm mark. Example 2: The illustration in figure below shows a uniform metre rule weighing 30 N pivoted o..

The ordinary magnetic effects in materials are determined by atomic magnetism. On continuing to cut a magnet into its smallest bit, we reach the level of a single atom. This is a tiny current loop in which the current corresponds to the circulation of the electrons in the atom. To this atomic curr..
