14. A column of mercury 2.0 meters long and at 20°C is enclosed in a plastic casing of inner diameter 3.65 mm. The resistivity of mercury is 98x102 m. a. What is the resistance of this tube of mercury? b. What happens to the resistance if the shape (length and radius both change but it stays circular in shape) of the column is changed so that the column is made 1.0 meter long using the same amount of mercury?
