Question

explain value of g is zero at the center of the earth. [it is from physics gravitation concept ] pls give ans .....

Answer 1

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.
