In Millikan oil drop experiment, a charged drop of mass `1.8 xx 10^(-14) kg` is stationary between its plates. The distance between its plates is `0.90 cm` and potential difference is `2.0` kilo volts. The number of electrons on the drop is

In Millikan's oil drop experiment, a charged oil drop of mass 3.2xx10^(-14)kg is held stationary between two parallel plates 6mm apart by applying a potential difference of 1200 V between them. How many excess electrons does the oil drop carry? Take g =10ms^(-2)

A charged drop of mass 3.2 xx 10^(-12) g floats between two horizontal parallel plates maintained at potential difference of 980 V and separation between the plates is 2 cm. The number of excess or deficient electrons on the drop is

In the Millikan's experiment, the distance between two horizontal plates is 2.5 cm and the potential difference applied is 250 V .The electric field between the plates will be

In a Millikan's oil drop experiment, an oil drop of mass 4.9xx10^(-14)kg is balanced by a potential difference of 4000 V between two plates which are 8 mm apart. Find the number of elementary charges on the drop.
