Answer 1

Given,

Weight of man on earth W1 = 1200 N  Weight of man on moon W2 = 200 N 

Gravitational acceleration of earth = 10 m/s2 

Now, W = mg  Or m = W/g 

 = 120 kg So,

mass on moon will be 120 kg as it is constant everywhere

so mass of man on moon = 120 kg

$w = mg \\ 200 = 120 \times g \\ g = \frac{200}{120} \\ g = \frac{10}{6} = \frac{5}{3} \\ g = 1.66m {s}^{ - 2}$

Answer 2

Answer:

Given,

Weight of man on earth W1 = 1200 N

Weight of man on moon W2 = 200 N

Gravitational acceleration of earth = 10 m/s²

Now, W = mg Or m = w/g

= 120 kg so,

mass on moon will be 120 kg as it is constant everywhere

so mass of a man on moon = 120 kg

w = mg

200 = 120 × g

g = 200/120

g = 10/5 = 5/3

g = 1.66ms–²
