Question

The strength of magnetic force varies inversely with the square of the distance between the magnets. In other words,

Force=kdistance2Force=kdistance2 where kk is constant.

Suppose that when two magnets are 0.05 meters apart, there is a force of 4 newtons. Find the work, in joules, that is required to move the magnets from a distance of 0.010.01 meters apart to a distance of 0.10.1 meters apart. (1 Joule = 1 Newton * 1 meter) Round your answer to three (or more) decimal places.

WW=  Joules
