Question

A body has a mass of 1kg on the surface of
Earth. What is the mass at the centre of Earth?
(1) 0 kg
(2) 1 kg
(4)
(3) 9.8 kg​

Answer 1

Answer:

no the correct answer is option 1) 0 kg

Answer 2

Answer:

A correct answer is option (2). A body has a mass of 1kg on the surface of Earth and its mass at the centre of the earth is 1kg.

Explanation:

• Because mass is location-independent, a body with a mass of one kilogramme on the surface of the earth will have the same mass at its centre and everywhere else.
• The quantity of matter that makes up an object's body is known as mass.
• The fundamental unit of mass in the metric system and the global standard is 1 kg. The Kg was more precisely defined in 2019 in terms of the Plank constant.
• A fundamental physical quantity that is constant in the entire universe is mass.
• The indicator of gravitational attraction on a celestial body is weight instead.
• The mass remains constant in the Earth's centre then mass equals 1 kilogram
• As a result of the Earth's gravitational pull pulling in all directions at its centre, the weight = P = 0 while the mass is 1kg.

Thus, A body has a mass of 1kg on the surface of Earth. Its mass at the centre of the earth is also 1kg.
