Q&a Game For Fun !!! Ok... Just came across something weird and interesting in one of my physics books and I thought I'd share it and start one of those Q&A games I've seen on this forum! "When two parallel uncharged metal sheets are placed in a perfect vacuum, they attract each other with a tiny force that is not Gravitational. What is the source of this effect?" :surprised :surprised :surprised The person who comes closest to the solution can pose the next question!
