P6.1.2.4 Determining the Electric Unit Charge after Millikan and Verifying the Charge Quantification - Measuring the Rising and Falling Speed with CASSYDetermining the Electric Unit Charge after Millikan and Verifying the Charge Quantification Measuring the Rising and Falling Speed with CASSY In the variant P6. 1. 2. 2 and P6. 1. 2. 4, the oil droplets are observed which are not precisely suspended, but which rise with a low velocity v2. The following applies for these droplets: Additionally, the falling speed v1 is measured, as in the variant P6. 1. 2. 1 and P6. 1. 2. 3. The measuring accuracy for
