(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I've posted this in the homework section but really, it was asked by a young kid who had just been learning about gravity in high school science. It made my realise that I wasn't able to provide a superb answer.

So, you have a man standing inside a building, what is the gravitational force on him? Of course we are only talking about estimates and ball park figures here. If he were standing right in the middle of the building, and it had an evenly distributed mass, then it would be right to assume that the net gravitational force would be zero since it would all cancel?

What about if the person were right on the left edge of the building? I have so little idea about weights of buildings that I'm struggling to even think of a ball park figure.

2. Relevant equations

I have a hunch that F = Gm1m2/r^{2}will come into it...

3. The attempt at a solution

Right now I am thinking that "on average, the net gravitational force will be zero because the forces in each direction will all cancel out" but that sounds a bit unsatisfactory?

Cheers in advance for any help.
