A dehumidifier maintains the air moisture in the lab room at

A dehumidifier maintains the air moisture in the lab room at 50% relative humidity. Which method of pith ball charging should be used at this condition A student obtained fo the slope S (Eq. (3) in the text) of the graph \"d vs 1/r^2\' to the value 1.36. How many electrons did the pith ball gain when charged by induction if the series of measurements was performed with equal split of the initial charge with the suspended pith ball Necessary data are provided in the \"Analysis and Discussion\" part of the text.

Solution

1.Coulomb’s Torsion Balance method used to find the air moisture in the lab room

F2. or problem 2. Data is not provided. It is in the text. Which text ?.
