Weight on mars

$=m\times \frac{4}{10}m\mathrm{g}=\frac{4}{10}\times 200=80\mathrm{ }\mathrm{N}$

${\text{g}}_{\text{e}}=\frac{{\text{GM}}_{\text{e}}}{{\text{R}}_{\text{e}}^2}{\text{g}}_{\text{m}}=\frac{{\text{GM}}_{\text{m}}}{{\text{R}}_{\text{m}}^2}$

$\frac{{\text{g}}_{\text{e}}}{{\text{g}}_{\text{m}}}\frac{{\text{M}}_{\text{e}}·{{\text{R}}_{\text{m}}^2}_{}}{{\text{M}}_{\text{m}}{\text{R}}_{\text{e}}^2}=10{\left(\frac{1}{2}\right)}^2=\frac{10}{4}$

weight on mars =$\left(200\right)·\left(\frac{4}{10}\right)=8\mathrm{0 }\text{N}$
