An oil drop of mass `5xx10^(-15)` kg carries a charge Q. The drop is stationary between two parallel metal plates 25 mm apart with a p.d. of 1000 V between them. Determine Q. Take `g=10 ms^(-2)`.

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)

An ail drop having charge 2e is kept stationary between two parallel horizontal plates 2.0 cm apart when a potential difference of 12000 volts is applied between them. If the density of oil is 900 kg//m^(3) , the radius of the drop will be

In a millikon's oil drop experiment, an oil drop of mass 0.64xx10^(-14)kg , carrying a charge 1.6xx10^(-19)C remain stationary between two plates seperated by a distance of 5mm . Given g=9.8m//s^(2) , the voltage that must be applied between the plates being

An oil drop of 10^(-6) m radius carring a charge 4 times that of an election and remain suspended between two charged parellel plate .01m apart. Find the potential difference between the plates.

In a Millikon's Experiment and oil drop of radius 1.5 xx 10^(-6) m and density 890 Kg//m^(3) is held stationary between two condenser plates 1.2 cm apart and kept at a p.d of 2.3 kV . If upthrust due to air is ignored , then the number of excees electron carries by the drop will be

An oil drop having a mass 4.8xx10^(-18) g and a charge 2.4xx10^(-18) C stands still between two charged horizontal plates separated by a distance of 1 cm If now the polarity of the plates is changed, instantaneous accleration of the drop is (g=10ms^(-2)

An oil drop with charge 1.6xx10^(-18)C is balanced in air between two metallic plates 10 mm apart. Calculate the voltage required between the plates if mass of the drop is 2.4xx10^(-14)kg .
