electrostatic charges

The electric field where ' s ' is the surface charge density and the unit vector normal to the surface in the outward direction. Choose a small cylinder, which is partly inside and partly outside the surface of the conduc..

Sulphur is a non-conductor of heat and electricity. However, a lump of sulphur when rubbed by dry hand, or with wool, becomes electrostatically charged..

Gauss's theorem in electrostatics indicates that isolated charges exist and that electric lines of force do not form closed loops. The situation is different in magnetis..

Bonding in a complex ion is due to electrostatic interactions between the positively charged nucleus of the central metal ion and electrons in the ligands i.e., attractive as well as repulsive interaction..

Conductors have free electrons. Electrostatic field inside a conductor is zero. At the surface, electrostatic field is normal to the surface at every point. Electrostatic field at the surface of charged conductor is given by ..

Electrovalent substances are made up of ions in the solid state. The oppositely charged ions are held together by strong electrostatic (coulombic) force of attraction. Due to these forces the ions cannot mov..

: is the work done at a point by an external agent in moving a unit positive charge from infinity to a given point against the electrostatic field. ..

Ionic bond: 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 bon..

In electrostatic situations, the electric field is zero everywhere within the conductor, and there is no current. This does not mean that all charges within the conductor are at res..

Bonding in a complex ion is due to electrostatic interactions between the positively charged nucleus of the central metal ion and electrons in the ligands i.e., attractive as well as repulsive interactions. (i) The attractive forces will arrive due to the positive metal ion and ..
