Two positive charges are seperated by 12 cm. the force thatq1 exerts on q2 is 4×10 ^8n. what is this force if the distance between the two charges is reduced to 9cm?

The new force is 7.11 x 10^8 N.

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.
