Answer:
Given :-
Weight of person on earth = 750 N.
W = mg
m = 750/g
Mass of Moon = Mm = 1/81 Me
Radius of Moon = Rm = 1/3.7 Re
As we know that,
gm = GMm/(Rm)²
gm = G(1/81 Me)/(1/3.7 Re)²
gm = 0.169[GMe/(Re)²]
gm = 0.169 g
Wm = m.gm
Wm = 750/g × 0.169 g
Wm = (750 × 0.169)N
Wm = 126.75 N
Hence,
The weight of person on Moon = Wm = 126.75 N
