How much will a person with 72N weight on the Earth,weight on the moon a)12N,b)36,c)21N,d)63N
Answers
Answer:
12 N
Explanation:
The person will weigh 1/6
⇒ Weight on moon = 72*1/2 = 12 N
The weight of the man on moon will be a) 12 N
The weight of the man on the Earth = 72 N
Weight of any object or living being = mg
Where m = mass of the object or that living being
g = acceleration due to gravity
We know, the mass of any object is always constant (apart from the situation of Einstein's relative motion).
So, after going to the moon, the mass of the man will also remain constant.
Only the acceleration due to gravity will change.
Now, the acceleration due to gravity on the moon is generally 1/6th of the acceleration due to gravity on the Earth.
So, the weight of the man will also be 1/6th of the weight as measured on the Earth.
∴ The weight of the man on the moon will be = 72 × (1/6) N
= 12 N
