My question arises from this post by Ashish Arora, where he asks: "If $g$ becomes zero suddenly, a body at rest on a fixed table will start moving away from it."
In the above question $g$ is the acceleration due to gravity.
Some in the comment section have stated that the body will fly away due to the loss in the centripetal acceleration provided by the earth's acceleration due to gravity.
Others have mentioned that Normal force is 'self-adjusting' and that if the acceleration due to gravity is zero, then the force experienced by the body towards the earth's centre is zero and there won't be any normal force.
I've been taught that if any two bodies are in contact, no matter what, they will experience 'some' contact force, due to the electromagnetic forces between the two surfaces in contact. So I would say that it does in fact leave the table (even the distance might be absolutely minuscule.)
So, who is correct. Was I taught wrong? (I guess it's more complex than a right or wrong answer though.)
