Description

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 the charge q can be increased by causing the oil droplet under study to rise and fall over a given distance several times in succession and measuring the total rise and fall times.
