Constants part a wo charged dust particles exert a force of 7.5x102 n n each other what will be the force if they are moved so they are only one-eighth as far apart? express your answer using two significant figures.

New force,

Explanation:

It is given that,

Force acting between two charged particles,

We need to find the force if they are moved so they are only one-eighth as far apart.

The force between two charged particles separated at a distance of r is given by :

............(1)

If the charges are one-eighth as far apart then, r' =(1/8)r and new force is given by :

..........(2)

Dividing equation (1) and (2) :

F' = 48000 N

or

Hence, this is the required solution.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
