Two point charges are separated by 10.0 cm and have charges of +2.00 µC and -2.00 µC, respectively. What is the electric field at a point midway between the two charges?

Explanation:

Let consider that electric field lines from positive charge (element 1) moves away in a radial direction, whereas lines from negative charge (element 2) get closer in radial direction. Besides, let assume that the positive charge (element 1) is located on the right and the negative charge (element 2) is located on the left.

Lastly, let consider that any vector facing right has a positive direction and any vector facing left has a negative direction. The net electric field is obtained by applying the Principle of Superposition:

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

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 =
