Mass of the body is always same but weight equation is given below:
F=GM m/r^2
We know that F= m x a
m x a = GM m / r^2 here a is acceleration due to gravity
a=GM/r^2
= (6.67×10^-11) × (6.46×10^23) / (3.39 × 10^6)^2 = 3.749 m/sec^2
So now to find weight of 75 kg person on mars .
F= m x a = 75 x 3.749 = 281.175 N
F=GM m/r^2
We know that F= m x a
m x a = GM m / r^2 here a is acceleration due to gravity
a=GM/r^2
= (6.67×10^-11) × (6.46×10^23) / (3.39 × 10^6)^2 = 3.749 m/sec^2
So now to find weight of 75 kg person on mars .
F= m x a = 75 x 3.749 = 281.175 N
