Question

*3.
Explain why the value of g is zero at the
centre if the earth​

Answer 1

Answer: g is 0 at Centre of the earth

Explanation: because when we are at the surface of the earth there are value of g is 9.8 m/s square but when we start to go into the earth surface then the value of g start decrease. Because the gravitational face reduces and it is 0 at the center.

Answer 2

Acceleration due to the earth's gravity is zero at the centre of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. ... At the centre the distance is zero, hence gravity is zero.
