If a projectile is sent from the surface of the earth,then its escape velocity is (under root 2GM/R).But if the same is projected from the centre of the earth,then what would be is escape velocity?

any motion inside the earth is simple harmonic.hence when u throw a body at the centre of the earth it has max velocity at the centre of the earth(mean position).Its velocity continuously decreases and its velocity is 0 at the surface of the earth(extreme position)and u would need to project it with escape velocity to overcome the gravitational force.
