Heya_______________________________
Here is your answer.....
The acceleration due to gravity is roughly 9.8 m/s^2 .
At the surface of the earth , it's same as 9.8m/s^2...
Let , consider g be acceleration of gravity , if we have g on earth surface is 9.8m/s^2. At the very center, the gravitational force is zero because there's equal mass pulling on you from all sides, and it all cancels....
Hope this helps!!!

Hi Anita !!
We know that the value of g at a place on the earth is inversely proportional to the square of the radius at that place.
g is = GM/(R)^2
Clearly g is = 1/(R)^2
At the centre of the earth , the radius is negligible or 0.
Therefore the value of acceleration due to gravity is 0 at the centre of the earth !!
Also , at the centre of the earth the mass is equally distributed in all directions such that it experiences an equal pull from all directions resulting in a net zero pull.
This also explains why the acceleration due to gravity becomes zero at the centre of the earth.
Hope that clears your doubts Anita !!
