electrostatic charges

Crystal Field Theory - 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 ..

Electric Field - The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that point. If is the electrostatic force experienced by a test charge q at a point, then the electric field intensity a..

is a means by which electrical energy is transferred from one place to another for utilisation. Charges in motion constitute an electric current. We know from electrostatics that when an isolated conductor is placed in an electric field, the charges in the conductor ..

While charging a capacitor, a battery transfers positive charge from negative to the positive plate. So some work is done in transferring this charge, which is stored in the capacitor in the form of electrostatic energy. This energy can be recovered by discha..

Electric charge is a basic property of all matter. Unlike charges attract, like charges repel. Conductor allow flow of electric charges through them while insulators don't. Electric charges have three basic properties (a) Additivity (b) ..

Explanation of Induction - When the positively charged body is brought near the two cans A and B, the electrons (-ve charges) from both the cans are attracted and get concentrated on B which is near R. The can A which has lost the electrons is left with an equal amount of positi..

It states that "the electrostatic force between two electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them ..

Dipole-dipole interactions These types of forces occur in molecular solids which have polar molecules. A polar molecule has separate centres of positive and negative charges. These forces arise due to electrostatic attraction of the other molecule and vice-versa (Th..

Photocopier - Then term 'Xerography'; the use of Photoelectric phenomena to transfer an image from one sheet of paper to another comes from the Greek words for "dry" and "writing". Dry copying is based on the principle that materials with opposite electrical charges attract one another an..

Magnetism and Gauss's Law - 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 magnetism. The Gauss's law in magnetism therefore will ..
