i was absent the day the teacher gave us notes on how to do these problems. it would be sooo helpful if someone could show me how to do some of the following problems, or just offer a brief explanation. thanks so much

1. two hundred years ago, boys were employed on warships and called powder monkeys. their task was to run sacks of black gunpowder from below deck to the cannons on decks. it was ship law that these powder monkeys worked barefoot. why would this be so?

2. if you scuff electrons onto your socks as you walk across the rug, then are your feet negatively or positively charged? what about that area of the rug?

3. a single electron (mass 9.1 x 10^-31 kg) and a single proton (mass 1.7 x 10^-27 kg) within a hydrogen atom are sperated by a distance of 5.3 x 10 ^-11 meters. if these both have the equal, but opposite charges of 1.6 x 10 ^-9 coulombs, then :

a. what is the electrostatic force between them?

b. what is the gravitational force between them?

c. how many times larger is the electrostatic force than the gravitational force?

ill post some more in a minute or so...
