Question

◕ Explain why the value of "g" is zero at the centre of the earth .​

Answer 1

• At the centre of Earth, the force due to upper half of the Earth will cancel the force due to lower half.

• Therefore, when F=0, then g has to be 0. Thus, the value of g is zero at the centre of Earth.

Answer 2

g is equal to 0 because distance is equal to 0
