A particle with a charge of 34.6 $\mu C$ moves with a speed of 68.4 m/s in the positive $x$ direction. The magnetic field in this region of space has a component of 0.466 T in the positive $y$ direction, and a component of 0.876 T in the positive $z$ direction. What is the magnitude of the magnetic force on the particle?

The magnitude of the magnetic force on the particle is 67.86 N.          

Explanation:

Given that,

Charge,

Speed of particle, v = 68.4 m/s in +x direction

Magnetic field,

We need to find the magnitude of the magnetic force on the particle. The magnetic force is given by :

The magnitude of magnetic force on the particle is :

So, the magnitude of the magnetic force on the particle is 67.86 N.          

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 =
