If a block has a mass of 10kg and weight of 60 lbs what would its mass and weight be on the moon

Mass is a constant, howver weight is not constant on planet becuase the gravitational force is directly proportional to the acceleratoin due to gravity (gravitational constant). The force on gravity is shown on a scale and equal to weight

I'll be using the gravitational constant of the moon 1.6m/s² OR one can calculate the graviational constant on the moon, using the equation for universal gravitation

Using Newton's second law we can find weight, F (F-force of gravity)

F=ma                  We can deduct that mass is constand and a=g
F=mg                  Insert value of g, mass (constant)
F=10(1.6)       
F=160                 Weight=F
Weight=160 kg

In conclusion, a 10kg object has a mass of 10kg and 160 kg weight on the moon

The answer is option b.
