Gravitational Cancellation at Earth’s Center
At the center of the Earth, the value of ( g ) (acceleration due to gravity) becomes zero due to the cancellation of gravitational forces.
Spherical Symmetry and Gravitational Pull
The Earth’s mass distribution creates a symmetrical gravitational force that acts uniformly in all directions.
Balancing Gravitational Forces
Gravitational forces from all points on the Earth’s mass pull in opposite directions toward the center. This results in a cancellation of these forces at the core.
Net Effect at the Center
Due to this balanced gravitational force from all directions, the net effect at the center becomes zero. The forces pull equally from all sides, resulting in no net gravitational pull, making the value of ( g ) zero at the center of the Earth.
