Charge to Mass Ratio (e/m) of an Electron

The uncertainty value was also estimated for the parameter values to for comparison purposes. The table shows that the uncertainty value for R decreases as the measured R increases. The average e/m value is also calculated which is 8.9x10^7. There is a great disparity with this value with the theoretical value for the e/m. Possible errors can be due to the precision and accuracy of the measurements taken through the set-up such as the measuring of the radius, set-up of the voltmeter and amp-meter, and other possible ...Show more


Based on the tabulated results having six trials the measured radius increases as the voltage and current goes higher. The voltage used is from 150 V with…

Mass Spectrospcopy
The positive components that result from this electron bombardment are then accelerated into a vacuum through a magnetic field. It is in this magnetic field that the components are eventually sorted on the basis of mass to charge ratio. Because a majority of the ions produced in the mass spectrometers are positively charged, they are cations; these ions tend to carry an overall unit positive charge.

The quick ratio is similar to the current ratio, but is a more conservative measure of a company's liquidity. It considers only most liquid assets (it does not include inventory since inventory is not easily liquidated). The formula is: [(current assets) - (inventory value)] / (current liabilities).

Mass spectroscopy and Raman spectroscopy
A spectrum is a portion of the energy level which was detected against the wavelength of the energy. A spectrum is used to derive information on atomic and molecular energy levels, interactions of molecules, molecular geometries, and chemical bonds. In qualitative analysis, the resulting spectra are used to classify the components of a sample, while in quantitative analysis, spectra is used to measure the amount of material in a sample.
