Physics Statue Of Liberty?

Question

Calculate the weight of the Statue of Liberty (205 tons) on Earth. The Earth has a mass of 6 × 10^24
kg and a radius of 6.4 × 10^6 m.
Answer in units of N.

Answer 1

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
