what will be the mass and weight of the person on earth and mars?​

the mass of the person will remain same in earth and mars

but there will be difference in weight due to gravitational force

Heya

Weight=mass×surface gravity multiplying your weight on earth will give you your weight on the surface of each planet..

If you weigh 150 pounds. i.e(68kg) on earth you would weigh a mere 9lbs .i.e. (4kgs) on mars...

Hope this will help you out..
