An experiment was carried out twice using magnetic deflection type mass-spectrometer to estimate a certain molecule present in the compound under test. In the first test, the sample was excited and the potential difference between the accelerating plate was kept at 1000 V and in the second case, the potential difference was at 10000 V.
