Problem

A spring balance calibrated on Earth (where

1\,\text{kgf} = 9.8\,\text{N}

) is taken to Planet X, where the acceleration due to gravity is

12\,\text{m/s}^2

. When an object is hung from the balance, it shows a reading of

15\,\text{kgf}

. What is the mass of the object? a)

15\,\text{kg}

12.3\,\text{kg}

18.4\,\text{kg}

14.7\,\text{kg}
