Dear Student,
weight of the body on the surface of a planet is given by,W=mgweight of the body on the surface of the earth is given by,W=mg=5
6 kgwthere,g is acceleration due to gravity on the surface
for earth,g=GMR2
(i)for the another given planet,M'=M7 and R'=R2g'=GM'R'=GM7R22=GM7R24=47GMR2=47g
(ii) weight on the surface of the given planet,W'=mg'=47mg=47×5
6=3 2 kg wt
