explain the term electrostatic pressure?

Answer 1

Pressure is just force per unit area. So the electrostatic pressure is the force per unit area that electric charges exert on an object.

Answer 2

Electrostatic Pressure

Answer 3

The best example I can think off is an electrostatic speaker.

Simple explanation: A very thin and flexible diaphragm is placed near a grid of rigid wires. The grid is fed a steady high voltage which creates an electromagnetic field and the audio signal is fed across the diaphragm which sets up the electrostatic force between the diaphragm and the wires - this force is in direct relation to the audio signal and the diaphragm is pushed and pulled by the electrostatic forces developed between the rigid wires (which cannot move) and the flexible diaphragm (which moves in direct relation to the audio signal).

These speakers are incredibly accurate at converting an electrical signal into sound waves.
They do not suffer the drawbacks of induced currents inherent with magnetic speakers.

Answer 5

This probably refers to what is now called electrostatic voltage. Pressure is a term from olden days meaning voltage.

Solids, whether pure elements or in general, are crystals made up of ions or molecules, or in rare cases like diamond a single compound of covalent bonds. The thermal stability of a crystal depends on the electrostatic (electrical charge, dipol or quadrupol) property of the constituents and their orientation, as well as their ability to retain constituents placed on the surface to the liquid. Electrostatic forces depend on the charge (or partial charge in case of dipols) and the inverse squared distance of the charges. Quadrupol forces aka Van der Waals forces depend on the inverse sixth potency of the charge. Usually crystals made up of molecules break up into single molecules when melting. In the liquid these molecules still interact with each other, until at boiling point these interactions aren't strong enough to retain the molecules in the liquid. Crystals made up of ions create ionic melts held together by electrostatic attraction. This isn't found for pure elements, though. Metals are similar in the liquid and solid state, with ionized atoms surrounded by a dislocated electron cloud. Covalently bonded crystals don't melt, but may transform into different compounds. Note that most elements have several different solid states. Elemental carbon can be found as monomer or low-count polymer fragments in the gaseous phase, no liquid phase (except Buckminster Fullerenes) that I know of and several very different solid phases: graphite (thermodynamically most stable form), diamond, and Buckminster Fullerenes and variations thereof which don't really behave like a solid. Several gaseous elements have no known solids at normal pressure. Iodine has no liquid phase at normal pressure. In a very general sense, the stronger the attractive forces between the elemental constituents, the more stable the solid/liquid phase. Covalently bonded elements tend to have higher melting points than metals, which in turn tend to have higher melting points than elements occurring in distinct molecules. Quite often the solid and even liquid phases include a change of atomic structure and nature of the bonds. Even in the gaseous phase, sometimes pairing of neutrally charged molecules may occur.

Answer 7

when a body has static electric charge and has a sharp point , then electroc charge concentrates at sharp point and this means electrostatic pressure but i ask why they concentrate at sharp point?
