Question

A person would have a different weight on each planet. Arrange the planets in increasing order based on a person’s weight on the planet.
Planet Gravity (m/s2)
Earth 9.8
Mercury 3.7
Neptune 11.2
Uranus 8.9

Answer 1

Answer: Mercury<Uranus<Earth<Neptune

Explanation: Weight is the downward force acting on an object due to gravity.

$w=m\times g$

w= weight of an object

m= mass of object

g= gravity

As the person has a constant mass, the weight differs due to the value of gravity (g). The planet having highest gravity would make a person weigh the most.

As the value of gravity varies: Mercury (3.7)<Uranus(8.9)<Earth(9.8)<neptune(11.2),  the weight of the person varies in the same order: Mercury<Uranus<Earth<neptune.

Answer 2

Mercury, Uranus, Earth, Neptune.

Hope this helps!
