Question

What is the gravitational force at the
centre of the earth?​

Answer 1

Explanation:

At the very center, the gravitational force is zero because there's equal mass pulling on you from all sides, and it all cancels. If you built a room there, you could float around freely. That's what it means to say that gravity is zero at the center of Earth. However, the gravitational well is a different story.
