Two point charges are brought closer together, increasing the force between them by a factor of 22. by what factor did their separation decrease? hint: if the force increases, distance between charges must decrease. force is indirectly proportional to the distance squared.

0.21

Explanation:

Given

Two point charges are brought closer together, increasing the force by a factor of 22

Let the original force be

where are charges and r is the distance between them

new force

divide 1 & 2

Distance between them is decrease by a factor of 0.21

gravity

explanation:

ice to water 1 water to vapour 2 latent heat
