A student is investigative a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 1.80 fg (where a femtogram, fg, is 10^-15 g) as well as is swimming at a velocity of v = 1.00 m/s, with an uncertainty in the velocity of 8.00 %. E. coli bacterial cells are around 1 m (10^-6 m) in length. The student is supposed to examine the bacterium and make a drawing. But, the student having just learned about the Heisenberg uncertainty principle in physics class complains that she can't make the drawing. She claims that the uncertainty of the bacterium's position is greater than the microscope's viewing field also the bacterium is thus impossible to locate.
Define what is the uncertainty of the position of the bacterium?
