Mass of body is 25 kg. What is its weight in Newton on earth? The body is carried to a planet whose mass is two times the mass of earth and radius is half that of earth. What will be the mass and weight of body on the planet? ( Take the value of g on earth as 10 m s -2 )

weight = 25×10=250N
g=GM/R^2
so
g'=G×2M/(R/2)^2=GM/2R^2=g/2
Hence mass =25kg. (mass will same at every place)
and, weight will become=25×10/2=125N
g=GM/R^2
so
g'=G×2M/(R/2)^2=GM/2R^2=g/2
Hence mass =25kg. (mass will same at every place)
and, weight will become=25×10/2=125N
