Mass of the earth,Me=6 × 10^24

Radius of the earth,Re=6.4 × 10^6 m

Mass of the Statue of Liberty,m=205 tons=185972 kg

Gravitational constant,G=6.67 x 10-11 N-m2/kg2

-----------------------------------------

Weight of the Statue of Liberty,W=GMem/Re^2

                                                           =6.67x10^-11x6 × 10^24×185972/(6.4 × 10^6)^2

                                                           = 11629061.63 N
