Problem

A spring balance is calibrated in kilogram-force (kgf) under standard gravity

g = 9.80\,\text{m\,s}^{-2}

. When an unknown object is suspended from it at a hill station where

g = 9.75\,\text{m\,s}^{-2}

, the pointer shows a reading of

5.0\,\text{kgf}

. Answer the following: (a) Convert this reading into newton. (b) Determine the true mass of the object in kilogram. (c) What apparent mass would the balance indicate for the same object if it were taken to a place where

g = 9.90\,\text{m\,s}^{-2}

? a. (a) Convert the reading of

5.0\,\text{kgf}

into newton. c. (c) What apparent mass would the balance indicate for the same object at a place where

g = 9.90\,\text{m\,s}^{-2}
