Derive the version of maxwell's equations applicable to the electric and magnetic fields in an ohmic conductor ( = oe, p = 0). show that a solution of these equations consists of a travelling wave part, multiplied by an exponential attenuation with depth into the conductor.

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 =
