electrostatic charges

Consider two points in an electric field. If a free test charge +q o was placed in the field, it would flow from b to a. So we say b is at higher potential. The electric field does negative work in moving the test charge q o from a to b. If a and b are two poi..

To control the outflow of particulates at their industrial source of origin is the most effective and efficient method of control. This is achieved by the use of electrostatic precipitator. It is based on the principle that all particles acquire an electrical charge when expose..

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

In spite of the strong electrostatic force of repulsion between protons, nucleus of most elements are stable. This is because of the strong forces of attraction, which hold together the nucleons in that tiny volume. These forces are short-range forces and are the strongest in nature. The..

. 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. It now..

. 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 charged. Due to the attractive electrostatic forces, the Zn i..

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..

Just as the electric field is described as force per unit charge, electric potential at a point can be described as electrical potential energy per unit charge. This concept is useful in calculations involving energies of charged particles. Not only that, as force is ..

Hydrogen Bonding - 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..
