In Millilan's experiment , the oil drop acquire charge by

In Millikan's experiment, an oil drop having charge q gets stationary on applying a potential difference V in between two plates separated by a distance 'd'. The weight of the drop is

In the Millikan's experiment, the oil drop is subjected to a horizontal electric field of 2 N//S and the drop moves with a constant velocity making an angle of 45^(0) with the horizontal . If the weight of the drop is W , then the electric charge, in coulomb, on the drop is

In the Millikan’s Oil Drop experiment, the oil drop is subjected to such forces whose nature does NOT fall under the category of:

In Millikan's oil drop experiment an oil drop carrying a charge Q is held stationary by a potential difference 2400 V between the plates. To keep a drop of half the radius stationary the potential difference had to be made 600 V . What is the charge on the second drop ?

In Millikan’s oil drop experiment , a drop of charge Q and radius r is kept constant between two plates of potential difference of 800V. Then charge on other drop of radius 2r which is kept constant with a potential difference of 3200 is

In Millikan's experiment, static electric charge on the oil drops has been obtained by shining X-rays. If the static charge on the oil drop is -1.282xx10^(-18)C , calculate the number of electrons present on it.

In Millikan's oil drop experiment, an oil drop mass 60 xx 10^(-6) kg is balanced by an electric field of 10^(6) V//m . The charge in coulomb on the drop, assuming g = 10 m//s^(2) is
