Question

If I consider that a planet is having same density everywhere and is small in size. Then if I assume that density of a stone on that planet = density of planet. Is it correct and why?​

Answer 1

Explanation:

let's make your planet which is made up only rocky particles.

generally how you measure the density of a rock.1st you pick it up and measure weight and volume ,then we get density by weight/volume.

if you agree with me how we measure density we get a point there.You should pick a stone to measure it's density.Its on your hands how much volume and weight the stone has.If you pick up a small stone which has small volume definitely it's density won't be same as density of planet.

we can now see that density of stone doesn't depend on its presence on the planet it depends on its weight and volume.

by the way good question
