How much electric force is there between a charged object and a neutral object 1. none
2. a little since the neutral object becomes charged by induction

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%

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 =
