What would gravity feel like at different points on Earth if there was a super massive object near Earth?
I know it would depend on the mass of the object, but what I'm wondering is could there be a scenario where gravity appeared to be zero at any of the points on Earth?
For example, could point B ever feel like they're in freefall? Or would they simply feel 1G? (Earth and everything on it may be in "freefall" toward the black hole, but Earth still exerts its own gravity?)
I'm assuming that Earth is not orbiting the black hole, or the other way around. I'm not making assumptions of distance or mass, I'm more wondering if we could tweak the assumptions about distance or mass to get a zero-G effect at any point on Earth.
