In millikan's experiment an oil drop is found

WebThis experiment first described in 1913, is based on the fact that different forces act on an electrically charged oil drop moving in the homogeneous electric field of a plate capacitor (Fig.1). Going through the capillary of the atomizer, the oil droplets acquire electric charge due to friction. The effect is known as triboelectri c charging. WebCathode Ray Experiment. J. J. Thomson discovered the existence of electrons. ... The Millikan’s Oil Drop Experiment was an experiment performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the charge of an electron. In the experiment, Millikan allowed charged tiny oil droplets to pass through a hole into an electric field.

Web5 mai 2015 · By measuring the rate of fall, Millikan was able to measure the fall of the oil droplets (which were dropped through a tiny hole in the upper electrical condenser). In Newtonian physics, the rate of fall (or velocity) of a freely falling body does not depend on the mass of the object. So, how did Millikan measure the mass of these oil droplets? Webthe viscosity of air, the radius of the oil drop, the electric eld strenght, the terminal velocity of the drop in the presence of an electric eld and the (terminal) velocity of the drop in the absense of the electric eld. Remember that is negative! The drop radius can be found from the terminal velocity without electric eld, ! " # $&%('*),+ (2)
