Answer:
At the center of the Earth, the gravitational field strength experienced by an object of mass M would be:
O Zero
Explanation:
At the center of a spherically symmetric mass distribution, such as the Earth, the gravitational field strength due to the mass distribution cancels out in all directions. This is because the mass distribution exerts gravitational forces in all directions, but these forces cancel each other out at the center, resulting in a net gravitational field strength of zero. Therefore, an object located at the center of the Earth experiences zero gravitational field strength.
