Question

Question 47:
An object has mass of 20 kg on earth. What will be its (i) mass, and (ii) weight, on the moon ? (g on moon = 1.6 m/s2).

Answer 1

THE MASS WILL REMAIN THE SAME EVERYWHERE SO ITS MASS ON MOON WILL BE 20 KG.
ITS WEIGHT ON MOON WILL BE =   20 x 9.8 x 1/6
=32.6666666667N

Always remember that mass does not depend on its surrounding but weight depends on its surroundings

Hope it helps you ☺️

Answer 2

Hey, here is your answer.....

Given..., mass of the object on the earth is 20kg....

(i), mass of the object remains constant everywhere in the universe so the mass of the object on the moon remains same as that measured on the earth, i.e, mass of the object on the moon is 20kg...

(ii), weight is nothing but mass × acceleration due to gravity...

Given, to calculate the weight of the object on the moon....

And, given acceleration due to gravity on the moon is 1.6......

Then, weight of the object on the moon is equal to mass× acceleration due to gravity on the moon...

= 20×1.6
= 2×16
= 32N...


hope it helps you....
