Consider a container of 2.0 g of hydrogen, H2 (one mole). Suppose you removed all the electrons and moved them to the other side of the earth
 
  (Earth's radius is 6380 km, k = 1/40 = 9.0  109 N  m2/C2, NA = 6.022  1023 molecules/mol, e = 1.60  10-19 C)
  (a) How much charge is left behind after you remove the electrons?
  (b) What electric force do the protons exert on the electrons after they are separated as described?
