Question

a man weighs 510N on earth. what is his mass? (take g=10ms^2)if he were taken to the moon his weight would be 85N.what is his mass on the moon?what is his acceleration due to gravity on the moon. please answer​

Answer 1

Weight on earth = 600N

Let g= 10m/s

2

on earth

Mass on earth =

10

600

=60 kg

Now, since mass is a constant quantity so, it will remain 60 kg on the moon also.

Now, weight on moon = mg

′

m= mass =60 kg

g

′

= acc. due to gravity on moon =

6

1

th

the value on earth

So, Weight on moon =

6

1

th

of the weight on earth

⇒ Weight on the moon =600×

1

=100 N
