Explanation:
Generally the force of attraction between this two irons is mathematically represented as
![F = \frac{k * [Q_{Li} ] * [Q_{O} ] }{ r^2}](https://tex.z-dn.net/?f=F%20%3D%20%20%5Cfrac%7Bk%20%2A%20%20%5BQ_%7BLi%7D%20%20%5D%20%2A%20%5BQ_%7BO%7D%20%20%5D%20%20%7D%7B%20r%5E2%7D)
Here k is known as the proportionality constant with value 
substituting -2 for
i.e the charge on oxygen , +1 for
i.e the charge on Lithium and
for r
So


Generally the force of repulsion will be the magnitude but different direction to the force o attraction
So Force of repulsionn is

Answer:
Insulation helps to prevent that transfer of heat.
<span>One astronomical unit is equal
to the average distance between the Earth and the Sun. The answer is letter B. However,
the distance between the earth and the sun varies as the earth revolves around
the sun. but recent discoveries have proven the exact distance. It is also
equal to 149, 597, 870, 700 meters and was defined by the International
Astronomical Union. </span>
