The correct option is A 1.66 ms−2
Weight of man on earth, w = 600 N
Acceleration due to gravity on earth, g=10 ms−2
Mass of man on earth, m=60010
m = 60 kg
We know that, mass remains constant everywhere.
Therefore, mass of man on moon, m = 60 kg
Weight of man on moon, w = 100 N
Acceleration due to gravity on moon is,
g=wm
g=10060
g=1.66 ms−2
