Yes Gravity is zero at Center of Earth..
At center of earth Distance From Center to Point of action ( where the object is placed ), 'd' is '0'.
Hence, The mass of Earth which forms Gravitational force is Zero. Since
4/3πd^3 × density of Earth = 4/3π × 0 × 5.51 = 0.
Therefore, Gravity at Center is Zero.
( It's not because of Gravitational force acting from all sides cancels each other. Since Gravitational force acts only from the center ).
