Which statements describe the factors affecting the strength of an electrical force? Check all that apply.

The weaker the charge on two objects, the stronger the electrical force between them.
The stronger the charge on two objects, the stronger the electrical force between them.
The charge of the two objects does not affect the strength of the electrical force between them.
The closer together two objects are, the stronger the electrical force between them.
The farther apart two objects are, the stronger the electrical force between them.
The distance between two objects does not affect the strength of the electrical force between them.

The closer together two objects are, the stronger the electrical force between them.

Explanation:

-- The stronger the charge on two objects, the stronger the electrical force between them.

and

-- The closer together two objects are, the stronger the electrical force between them.

chemical properties of thing

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 =
