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.

Heya !!!
Here is Your Answer.
Question : Why is the value of g or acceleration due to gravity is zero?
We know that as the distance from the Earth decreases, the acceleration due to gravity also decreases. So, at the centre, the distance is zero. So, the acceleration due to gravity will also be zero.
Secondly, Earth is rounded shaped. So, mass of Earth is equally distributed from all sides.
We know that if equal forces act on a body from opposite directions, then net force becomes zero. So, Due to mass of Earth equally distributed from all sides makes net force zero. That's why acceleration due to gravity at the centre of Earth is zero.
