Given that,

Mass, m = 1 kg

Mass of the Earth,
$M=6* 10^(24)\ kg$

Radius of Earth, r = 6378 km

To find,

The gravitational force.

Solution,

The formula for the gravitational force is given by :

$F=(GmM)/(r^2)\\\\F=(6.67* 10^(-11)* 1* 6* 10^(24))/((6378 * 10^3)^2)\\\\F=9.83\ N$

So, the required force is 9.83 N.
