Lec 04 Millikan’s Experiment Oil Drop, 11th Chemistry

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

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.

In Millikan's experiment, an oil drop of radius 10^(-4) cm remains suspended between the plates which are 1 cm apart. If the drop has charge of 5e over it, calculate the potential difference between the plates. The density of oil may be taken as 1.5 gcm^(-3) .

In Milikan's experiment , an oil drop having charge q, mass m , gets accelerated by applying a potential difference V in between two plates separated by a distance 'd' . The acceleration is

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
