1.   Two bodies have charge of -3 ´ 10^-9C and -6 ´ 10^-9C each.
      Both lie at a distance of 10 m away from each other. 
      What is the magnitude of Coulomb force between those two 
      charges?

2.   Two electrically charged bodies lie at a distance of 2 cm 
      from each other. If the first body has a charged of 4 µC 
      and the second body has a charged of -6 µC, what is the 
      magnitude of Coulomb force happening between those
      two charges?
