1. The problem statement, all variables and given/known data What interactions are at play in the following scenario, and what objects are involved in the interactions? A tiny bit of paper jumps from a tabletop toward an electrically charged comb. (Consider the bit after it has left the tabletop but before it reaches the comb.) 2. Relevant equations Use the following interaction categories: Gravitational, electrostatic, magnetic, friction, compression, and tension 3. The attempt at a solution It seems that the obvious answer is an electrostatic interaction between the bit of paper and the comb. But how does this interaction affect the paper's motion? Does it suck the paper like a magnet? And while the paper is in the air, what other interactions are at play? With gravity? Compression with the air, or friction with the air?
