<span>Hello, AphCoffee!
B. move from the negatively charged body to the positively charged body
This is because the negative free electrons will be attracted to the positive body and then the electrons will move to the positive body.
Hope this helps :)</span>

Answer:
F = 5.09 10¹⁰ q Q / a²
Explanation:
The electric force is given by Coulomb's law
F = k q₁ q₂ / r²
Let's apply this equation to our case, we have four force, the charge in the singer is positive Q, so the two upper charges have repulsive forces directed in the diagonals of the square and the two lower charges that are negative, have attractive forces directed at the length of the diagonals.
To find the total force we know how to use Newton's second law
On the x-axis we can see that all forces will cancel out
On the Y axis, all forces have the same direction, therefore the four forces are added.
We can find the value of one of them
The distance from the corner to the center of the square is
r² = (a / 2)² + (a / 2)² = 2 (a / 2)²
r² = a² / 2
Force is worth
F = k q Q / r²
F = k q Q 2 / a²
Let's use trigonometry to find the vertical component of this force
sin45 = / F
= F sin 45
= k q Q 2 / a² 07071
The total force is the
F = 4
F = k q Q / a2 8 0.7071
F = 5.09 10¹⁰ q Q / a²
A possible source of indoor air pollution is a gas present in some carpets and furniture, which is Formaldehyde and VOCs .
Formaldehyde can cause Cancer due to its exposure through the Furniture. These cause pollution inside the room acting as Indoor Air pollution gas.
By the end of seven days the concentration of formaldehyde in household furniture can be brought back to normal in most of the cases.
Whereas it is also known that it takes about two years for a well furnished newly made home to bring down the levels of evolved gas i.e. formaldehyde.
The following types of cancers are prone due to Formaldehyde:
- Nose
- Throat
- Sinus
Some Volatile Organic Compounds (VOCs) are found in desks in office, cabinet furniture and several products available as furniture. These chemicals are used in manufacture of new carpets harming our health.
VOCs can be removed by using hot water of the given carpet. These cause pollution inside the room acting as Indoor Air pollution gas.
It usually takes two to three days to evolve off the gas.
Hence, a possible source of indoor air pollution is a gas present in some carpets and furniture, which is Formaldehyde and VOCs .
