Question

the mass of a body is measured one planet earth as M kg.when it is taken to a planet of radius half that of the earth then its value will be a)4m b)2m c)M/4 d)M​

Answer 1

Answer:

$\bf{d) \: M}$

Explanation:

The mass of a body is measured on the planet earth as M kg.

When a body is taken to a planet of radius half that of the earth then the mass of the body is M because the mass does not change from place to place.

So, the mass of the body will be constant everywhere.

Mass of the body does not change another planet but the weight of the body will be change on another planet because weight depends upon the gravity.

Hence, The mass of the body will be M kg.
