    In case of earth, the impact of force of gravity is zero at the center of the earth. If you want to know why is it zero, then you must see the free wikipedia on gravity.

    In case of earth, the impact of force of gravity is zero at the center of the earth.


    See this relation below,


    i.e Effective Gravity ( g') = g ( 1 - d / R)


    where, d = depth of the earth


    & R = mean radius of the earth


    So, for the center of the earth, d = R,


    Hence, the net or effective gravity at the center of the earth is zero 


     i.e. g' = g ( 1-R/R) = g ( 1-1) = g × 0 = 0


    Hope this has helped you to some extent the above phenomenon. Share the idea with your friend too.


     

    Aint not it is neutral.
