A ball floats on the surface of water in a container exposed to atmosphere. Will the ball remain immersed at its initial depth or will it sink or rise some what if the container is shifted to moon?

Atmospheric pressure pushes downwards this is very large why you ignored this?

Yes answer is sink. I don't understand if atmospheric pressure vanishes so downward force reduces so it should come little upward.

Any ideas other people?
