The mass and weight of an object onearth are 5 kg and 49 N respectivelyWhat will be their values on themoon? Assume that the accelerationdue to gravity on the moon is 1/6thof that on the earth.c.Ans: 5 kg and 8.17 N

Answer»

Mass of the substance remains constant. It is the multiplication of density and volume that will remain unchanged in the whole universe. Somass of the object will remain 5 kganywhere in the universe. Weight has meaning only when an object having a specific mass is placed in an acceleration field, such as the gravitational field.

Weight = Mass x Gravitational Constant

Gravitational constant of Earth = 9.8m/s^2.

Therefore, an object having 5 kg mass will have weight of 49N on Earth.

Whereas, Gravitational Constant of Moon =1.622 m/s.

Therefore, the same object having 5kg mass will have weight of 8.11N.
