Question

Explain why the valu of g is 0 at the center of earth

Answer 1

At the centre the distance is zero, hence gravity is zero. The value of 'g' is 9.8.'g' is acceleration due to gravity.At the centre of the earth it will turn zero because there will be no acceleration at the centre of the earth.

Answer 2

the value of g is 0 at the center of earth because:

➡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. As the distance from the centre decreases, the acceleration due to gravity also decreases. At the centre the distance is zero, hence gravity is zero.
