there is no place on the earth where gravitational force is zero
santoshsuman:
at centre of earth
Near the surface of the earth.( sea, level)
no
at centre bro
you cannot be sure because there is no place at Earth where the gravity is zero. earth has mass and attracts everybody towards itself.

Theoretically, if you were standing in the exact spot that was the center of mass for the earth, the gravitational acceleration would be infinite according to the equation
g = (G(M1M2))/d12 where d12 is the distance between the centers of mass of the two bodies.
But if you are standing at the spot to which this infinite acceleration is attracting you, there’s no gravitational potential energy because you have basically fallen to the fall destination. So you would be really undergoing no external acceleration due to earth’s gravity and thus would not have any sensation of weight. Of course, you’d be impaled into extremely hot metal (the core), so you probably would have no sensations.
