Or imagine a planet of 100% water, with the block of steel at the center. What would be the big gravitational force on that block of steel, and which way would this gravitational field accelerate that block?  |
Pretty sure that if you do the math the point where the gravitational attraction is the strongest is somewhere partway to the core. It is increasing and you go deeper into the earth, up to a point, but it begins decreasing again.
