Re: ENERGY WITH Q



I forgot to add in my comments about not altering the spirit of the question:

You may *not* use a point particle model for the block or table. It
is a real block on a real table. I do not expect or require you to
model the actual interaction between the block and table. This is why
I only asked for the sign of the answer.
