The electrostatic force of repulsion exerted by one charged particle on another charged particle of the same sign. Also known as electrostatic repulsion.



Related Terms

COULOMB ATTRACTION

The electrostatic force of attraction exerted by one charged particle on another charged particle of opposite sign. Also known as electrostatic attraction.

ELECTROSTATIC FORCE

Force on a charged particle due to an electrostatic field, equal to the electric field vector times the charge of the particle.

COULOMB FORCE

The electrostatic force of attraction or repulsion exerted by one charged particle on another, in accordance with Coulomb's law.

ELECTROSTATIC VOLTMETER

A voltmeter in which the voltage to be measured is applied between fixed and movable metal vanes; the resulting electrostatic force deflects the movable vane against the tension of a spring.

ELECTROSTATIC FORCE MICROSCOPY

The use of an atomic force microscope to measure electrostatic forces from electric charges on a surface.

COULOMB POTENTIAL

A scalar point function equal to the work per unit charge done against the Coulomb force in transferring a particle bearing an infinitesimal positive charge from infinity to a point in the field of a specific charge distribution.

ENERGY INTEGRAL

A constant of integration resulting from integration of Newton's second law of motion in the case of a conservative force; equal to the sum of the kinetic energy of the particle and the potential energy of the force acting on it.

CONSERVATIVE FORCE FIELD

A field of force in which the work done on a particle in moving it from one point to another depends only on the particle's initial and final positions.

CENTRIFUGAL BARRIER

A steep rise, located around the center of force, in the effective potential governing the radial motion of a particle of non-vanishing angular momentum in a central force field, which results from the centrifugal force and prevents the particle from reaching the center of force, or causes its Schro dinger wave function to vanish there in a quantum-mechanical system.

CENTER OF ATTRACTION

A point toward which a force on a body or particle (such as gravitational or electrostatic force) is always directed; the magnitude of the force depends only on the distance of the body or particle from this point.
