Its weight would decrease and mass would remain the same
Explanation:
Mass refers to the amount of matter in an object while weight refers to the gravitational pull of an object due to gravity.
Mass is measured using a beam balance in kilograms while weight is measured using a spring balance in Newton.
Mass of an object remains constant everywhere and does not vary due to gravity while weight changes from place to place according to the gravitational pull of a surface.
Therefore, the weight of the radio will decrease on the surface of the moon because the gravitational pull is less compared to that on the earth's surface.
However, the mass of the radio will remain constant since mass does not change according to gravity.
