Question

Give Scientific Reason: The value of 'g' at the centre of the earth is zero.​

Answer 1

Answer:

At the centre of Earth, the force due to upper half of the Earth will cancel the force due to lower half. ... Thus, the gravitational force at the centre on any body will be 0. Since, from Newton's law, we know F=mg. Since, mass m of an object can never be 0.
