Question

The value of g on moon is 1/6th of its value on
the earth. If a person weighs 14 N on the
moon's surface, then the weight of the person
on earth's surface is
(A) 96 N
(B) 84 N
(C) 62 N
(D) 54 N​

Answer 1

Answer:

b) 84 is the right answer

Explanation:

weight of object on moon =14N

since ,

weight of object on moon=1/6th of weight on earth

therefore,

weight of object on earth =6*14=84N

Thank u!!

Answer 2

Correct question:-

The value of g on moon is 1/6th of its value on the earth.If a person weighs 14N on the moon's surface,then the weight of the person on surface is.

Given:-

•Weight of the person at the surface of moon(Wm)=14N

To find:-

•Weight on the person on earth's surface(We)

Solution:-

As we know that,we of an object on moon's surface is 1/6th of that of earth's surface.

Thus:-

=>Wm= 1/6We

=>14=1/6×We

=>We=14×6

=>We=84N

Thus weight of the person on the earth's surface is 84N and hence correct option is (B)

Some Extra Information:-

•Value of g at the surface of Earth is 9.8m/s²

•The weight of a body can be calculated by multiplying mass of the body with value of g of that specific place.

Thus:- W=mg

•Value of g at the surface moon is 1/6th of that of Earth.Thus,value of g at moon's surface is 1.6m/s².
