Abox is placed on a table. if an upward pulling force on the box is slightly less than the weight of the box, what will happen to the box? a) it will remain on the table. b) it will start to fall through the table. c) it will move upward briefly and then move downward. d) it will start to rise off the table and continue speeding up.

A for certain.

Explanation:

I got it right on the test, thanks to the other answerer teresecaway. But knowing the answer doesnt help much if you dont know WHY. The reason WHY is as follows. At first you might think it would be B, because the downwards force is greater than the upwards force. I thought that maybe upwards force would also count as the table supporting it, but no, thats just structural inanimate solid table. The answer is A. gravity would have to be HIGHLY raised or somebody pressing down on it, to make it fall through the table.
