mass of the man is same everywhere . so it is 80 kg.
but weight w= mg
here g(e)= 9.8 m / sec^2
g(m) =1.63 m / sec^2
so, w(e)= 80×9.8 = 784 Newton
w(m) =80×1.63=130.4 N
but weight w= mg
here g(e)= 9.8 m / sec^2
g(m) =1.63 m / sec^2
so, w(e)= 80×9.8 = 784 Newton
w(m) =80×1.63=130.4 N

Mass of the person = 80 kg
it is same on the Earth as well as on the Moon.
weight (force ) of the person on Earth = 80 kg wt = 80 kg * ge = 784 Newtons
weight of the person on the Moon = 80 kg * gm = 130.4 Newtons
