When the speed of electrons increases, then the value of its specific charge. View Solution. Assertion : When the speed of an electron increases its specific charge decreases. Reason: Specific charge is the ratio of the charge to mass. View Solution.
The specific charge of an electron, denoted as e / m, is defined as the charge, e, of the electron divided by its rest mass, m. This mathematical representation recognises the ratio of two fundamental properties of an electron: its negative electric charge and its rest mass.
Specific charge is the charge per unit mass of an object - this has units of C kg -1. For an electron, this is , where e is the charge of an electron and me is the mass of an electron. You need to be able to describe how specific charge is determined using: A magnetic field only. A magnetic field and an electric field. An electric field only.
The mass-to-charge ratio ( m / Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics .
Electrons have an electric charge of −1, and their mass is approximately about 1/2000 the mass of a neutron or proton. Electron charge is usually denoted by the symbol e. It is a fundamental physical constant that is used to express the naturally occurring unit of electric charge, which is = 1.602 × 10-19 coulomb.
The specific charge of an electron is a fundamental concept in physics that describes the ratio of the electron's charge to its mass. Denoted as \ (e/m\), this ratio is a constant for all electrons, with a value of approximately -1.7588 x 10^11 coulombs per kilogram (C/kg).
The electron specific charge is a physical constant equal to the electric charge of an electron (the elementary charge) divided by its mass: e/m e. It was first measured by J. J. Thomson in 1897, in what was arguably the first application of mass spectrometry.
Specific charge is the charge per unit mass of a charged particle. The equation for specific charge is specific charge = Q m \frac{Q}{m} m Q . The units for specific charge are Ckg-1.
Jun 4, 2024 · electron charge, (symbol e ), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10 −19 coulomb. In addition to the electron, all freely existing charged subatomic particles thus far discovered have an electric charge equal to this value or some whole-number multiple of it.
Specific charge is another title for the charge-mass ratio. This is a measure of the charge per unit mass and is simply worked out by worked out by dividing the charge of a particle by its mass. You can think of it as a how much charge (in Coulombs) you get per kilogram of the ‘stuff’.
