Which one of di following dey explain why di force of gravity wey dem measure for each ball dey almost di same?
Choose from:
 + Di final potential energy of each ball don increase..
 + Di amount of work wey dem need to carry each ball na di same..
 + Di distance wey each ball dey from Earth's center of mass dey almost di same..
 + Di gravitational force of each ball on top di other dey cancel out di force of Earth's gravity... Answer:``` <response>: ```Di distance of each ball from Earth's center of mass dey almost di same.```
