A boy in sunshine was heard saying that mass of a body on earth is equal to the mass on the moon,gravitational field strength on earth and moon are different •state whether the boy is correct??

The boy is incorrect. The mass of a body remains the same regardless of its location, whether on Earth or the Moon. However, the gravitational field strength on Earth is greater than on the Moon due to Earth's larger mass and size.

The boy is incorrect.

Mass is an intrinsic property of matter and does not change with location. It represents the amount of matter in an object.

However, weight, which is the force exerted on an object due to gravity, depends on the gravitational field strength. The gravitational field strength is stronger on Earth than on the Moon, which means that the same object will have a greater weight on Earth than on the Moon.

Therefore, while the mass of a body is the same on Earth and the Moon, its weight will be different due to the difference in gravitational field strength.
