Question

iii. A second astronaut has a weight of 600N on Earth. What would be his body mass on Earth?

Answer 1

Answer:100 N

Weight on earth = 600N

Let g= 10m/s²  

 on earth

Mass on earth =   600 /10

=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 =1 /6  th

 the value on earth

So, Weight on moon =  1  /6 th e of the weight on earth  

⇒ Weight on the moon =600× 1 /6  =100 N
