Question

You take a trip to the Planet Xero, whose gravity is one half of Earth’s.

(i) By what factor does your weight change on Planet Xero?

(ii) By what factor does your mass change?

assume g=10m/s^2

Answer 1

Ans (i)

We know weight W = MASS × gravity

So clearly if gravity is one half of the earth's gravity then weight will also be one half of earth on planet xero.

So weight will reduce by a factor 2 on planet xero

Ans (ii)

Mass is a fundamental property of any object

We can never change the mass of a body in any way.

So mass will remain the same on planet xero. Mass will not change.
