Questions on electrostatics

  1. Nov 5, 2012 #1
    i have read an example on electrostatics that if anyone rub a rubber comb and wool , the rubber comb acquires the ability to attract small pieces of paper . this is due to the comb becomes negetively charged and wool becomes positively charged . now the book tells that some electrons of the wool goes to the comb making the wool positive and comb negetive . now my question is how is it an example of electrostatic , as electrons are dynamic and it goes from wool to comb
