I suppose the "A" answer would be that if one knows the momentum of the electrons to the given degree of accuracy, one cannot then know the starting positions, and vice versa. Therefore, the question is unanswerable as it presumes an impossible level of knowledge about the location and motion of the particles.
The "B" answer is 1010. B+ if the answer is also given as 0A.
What's next? Math is much more entertaining than arguing about home schooling :-p
yeah 1010 or 10 in the base 10 system
