Problem

A spring scale reads

500\,\text{N}

when used on Earth’s surface. If the scale is taken to an altitude equal to Earth’s radius

R_E

and held at rest relative to Earth (ignore any orbital motion), which reading is most nearly expected? a)

250\,\text{N}

125\,\text{N}

62.5\,\text{N}

500\,\text{N}
