Two uncharged spheres are separated by 2.00 m. If 3.50 3 1012 electrons are removed from one sphere and placed on the other, determine the magnitude of the Coulomb force on one of the spheres, treating the spheres as point charges.

where is the circuit diagram ?

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 =
