First we make the relation between values
an object whose mass is 10 kg and weight is 20 N
and an object whose mass is 6 kg and the weight the missing value X
[tex]\begin{gathered} 10\longrightarrow20 \\ 6\longrightarrow x \end{gathered}[/tex]now we can use cross multiplication to find the value of x
x is the multiplication of the diagonal numbers (6 and 20) dividing between 10
[tex]\begin{gathered} x=\frac{6\times20}{10} \\ \\ x=12 \end{gathered}[/tex]the weight of the object is 12N
