Question

if a person mass is 10kg on surface of the earth so, what's the weight of that person on the earth surface​

Answer 1

Mass

Mass is the content inside the object which remains same everywhere.

Here mass = 10 kg on Earth

So the words 'On earth' wont matter here since mass will remain same even on Moon.

Value of g on Earth = 9.8 m/s^2

Since we know that,

Weight = Gravitational Force

Gravitational force = mg

Weight = mg

Weight = 10 kg × 9.8 m/s^2

Weight = 98 N

Answer : 98 N
