If the 50.0 kg boy were in a spacecraft 5R from the center of the earth, what would his weight be? (Use the 50.0 kg boy for significant figures)

i got 20N again not sure.. it dosnt tell me if i got them wrong or right online classes are horrible and very confusing

  • Physics - ,

    On the Earth
    mg=GmM/R²

    In the spacecraft
    mg'=GmM/(5R)²= {GmM/R²}/25=mg/25
    His weight is 50.0/25 =2.0 N
