To understand how to calculate forces between charged particles, particularly the dependence on the sign of the charges and the distance between them. coulomb's law describes the force that two charged particles exert on each other (by newton's third law, those two forces must be equal and opposite). the force f21 exerted by particle 2 (with charge q2) on particle 1 (with charge q1) is proportional to the charge of each particle and inversely proportional to the square of the distance r between them:

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

as technology advances, new experiments often expose problems in accepted theories. c

it doesn't. it was imagined up in the middle ages.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
