Question 1032109
The working equation would be {{{F = k/d^2}}}, for some undetermined constant.

To find k, We substitute the initial conditions in to the working equation:

{{{222 = k/4000^2}}} ==> {{{k = 3.552 * 10^9}}} lb-mi^2.

==> {{{F = (3.552 * 10^9)/d^2}}}

==> {{{F = (3.552 * 10^9)/4200^2 = 201.36}}} pounds, or 201 pounds to the nearest pound.
