Answer: Mercury<Uranus<Earth<Neptune
Explanation: Weight is the downward force acting on an object due to gravity.
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.
