Date: Page: In a millikan's oil drop experiment, a drop is observed to fall with a terminal speed 14mm is in the absence of electric field. When a vertical electric field of 4.9x105vim is applied, the droplet is observed to continue to move downward at a lower terminal speed 1.21 mmis, calculate the charge on the drop. CDensity of oil = 750 kg/m3, vis- cosity of air= 1.81x10-5 ighos, density of air=129 kg Im3) Solution Ans: 5,16810-19​
