Question 940384
If {{{F}}} varies directly with {{{m[1]}}} ,
then {{{F}}} has {{{m[1]}}} as a factor.
If {{{F}}} varies directly with {{{m[2]}}} ,
then {{{F}}} has {{{m[2]}}} as a factor.
If {{{F}}} varies inversely with {{{d^2}}} ,
then {{{F}}} has {{{1/d^2}}} as a factor.
 
If F does all of the above,
the product of all remaining factors can be called {{{G}}} , and then
{{{F=G*m[1]*m[2]*(1/d^2)}}} <---> {{{F=G*m[1]*m[2]/d^2}}}
