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​

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
