i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

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 [tex]= 2\%\hspace{1mm}of \hspace{1mm} 70\hspace{1mm} kg=\frac {2}{100}\times 70 =1.4\hspace{1mm} kg[/tex]

therefore, 100 trillion micro-organisms would weigh:

[tex]\rightarrow 100\times1.4 kg = 140 kg[/tex]

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 = [tex]\frac{1.4 kg}{10^12}=1.4\times10^{-12} kg[/tex]

Answer(b) both involve the use of levers;
