Question 714283
The force {{{F}}} is calculated by the formula
{{{F=G*(m[1]*m[2]/r^2)}}} ,
based on the masses involved,
{{{m[1]}}} and {{{m[2]}}},
the distance, {{{r}}} , between them,
and the gravitational constant,
{{{G=6.67*10^(-11)N(m^2/kg^2)}}}
 
{{{F=6.67*10^(-11)N(m^2/kg^2)*((7.0*10^30)kg*(1.0*10^9)kg/(5*10^3m)^2)=6.67*10^(-11)*7*10^30*1*10^9*Nm^2/25/10^6m^2=(6.67*7/25)*10^(-11+30+9-6)}}}{{{N=highlight(1.87*10^22)}}}{{{N=highlight(18.7*10^21)}}}{{{N}}}
The force is 18.7 hexillion Newtons.
I am using "hexillion" in the sense I learned in the USA.
Some countries may still use a different name for {{{10^21}}},
such as a thousand trillions, because sadly,
not even in math we can all agree,
and a billion used not to be the same number everywhere.
