why the value of acceleration due to gravity(g) is zero at the centre of the earth?

Expert Answer
The acceleration due to gravity is the measure of gravitational attraction that Earth exerts on a body. Now, this attraction is towards the centre of the Earth. That is, the Earth tries to pull every thing towards its centre. So, when the body is at the centre there is no need to pull it towards the centre anymore. So, acceleration due to gravity is zero at the centre of the Earth.
