electrostatic charges

These are the interparticle forces among the polar molecules. These forces arise due to electrostatic interactions between the oppositely charged ends of permanent dipoles. The positive end of one molecule attracts the negative end of the other molecule and vice versa as shown i..

The electrostatic force of attraction that is strong enough to hold together two unlike charges, namely a cation and an anion is defined as the ionic bond. In an ionic bond, A metal atom and a non-metal atom are involved. The metal atom loses electron/electrons, and a non..

Formulae and Facts - 1) Electric potential 'V' due to a point charge 'V' due to dipole (equatorial line) is zero. 2) P.d and electric fie..

Principle of electrostatics and electromagnetism play a very vital role in all modern scientific developments. Coulomb's law may be regarded as merely a special case of Gauss' law or we can say Gauss's law is generated form of Coulomb's law. Gauss' law makes it possible to calculate in a ..

. It is the 'potential difference' that is responsible for the flow of water. Similarly 'electrical potential' is the direction of the flow of charge. Let us consider the process of depositing an electric charge, for example, a positive charge on a neutral body. Initia..

These two processes will be taking place simultaneously at different rates. In this case, the rate of dissolution is found to be greater than the rate of deposition. Consequently, by the time equilibrium is reached, more of dissolution would have occurred and the solution becomes negatively ch..

Potential at a point due to a dipole along the axis - 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 charges..

The electrostatic force of attraction between the hydrogen atom of one molecule and more electronegative atom of the same or another molecule, is called hydrogen bond. When hydrogen atom gets bonded to atoms of highly electronegative elements such as fluorine, oxygen or nitrogen,the form..

. Let us push a box on a table (a rough horizontal surface). The motion of the box is opposed by the force of friction. The force of friction and the displacement of the object always make an angle 180 o and hence, the work done by the frictional force is always negative. When a positive charg..
