Problem

A block suspended from a spring balance reads

80\,\text{N}

on Earth, where

g=10\,\text{m}\,\text{s}^{-2}

. When the apparatus is taken to planet Z, the same block reads

60\,\text{N}

. If another block weighs

100\,\text{N}

on Earth, what will be its weight on planet Z? a)

60\,\text{N}

90\,\text{N}

75\,\text{N}

80\,\text{N}
