Consider a particle of mass m in a one-dimensional system (coordinate x) with attractive potential energy V (x) = − A (x 2 + a 2 ) s , (1) where A > 0, a > 0 and s > 0 are positive system parameters. Use the semi-classical (Bohr-Sommerfeld) quantization rule to find out for which values of exponent s this potential would support an infinite (as opposed to finite!) number of bound states. (You do NOT need to find those bound states to answer the question!)

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
