The weight of the astronaut at that planet will be "1600 N".

Let,

  • The mass of planet, [tex]M' = \frac{1}{2} M_\bigoplus[/tex]
  • The radius of planet, [tex]R = \frac{1}{2} R_\bigoplus[/tex]

here,

  • [tex]M_\bigoplus[/tex] = Mass of earth
  • [tex]R_\bigoplus[/tex] = Radius of earth

Now,

The gravitational acceleration of the planet will be:

→ [tex]g' = \frac{GM'}{R^2}[/tex]

      [tex]= \frac{2G M_\bigoplus }{R_\bigoplus ^2}[/tex]

      [tex]= 2g[/tex]

hence,

The weight will be:

= [tex]2\times 800[/tex]

= [tex]1600 \ N[/tex]

Thus the above answer is appropriate.
