Problem

An object shows different readings on spring balances because the acceleration due to gravity varies. (i) The object weighs

98\,\text{N}

on Earth where

g = 9.8\,\text{m/s}^2

. Calculate its mass. (ii) Find its weight on planet Y where

g = 12.5\,\text{m/s}^2

. (iii) Among mass and weight, identify which quantity is a scalar.
