We know,
F = Gm1m2 /r^2
In centre there is no value of r which is radium that means the force will be zero ,which is actually gravity or weight of a person.

Answer:
Acceleration due to gravity becomes 0. Weight is equal to mg. At the center of the earth, you experience zero net force since every mass particle is equally pulling on you in different directions that all cancel out. Thus, your acceleration is zero and therefore your weight is 0.
